Classical optics is divided into two main branches: geometrical (or ray) optics and physical (or wave) optics. In geometrical optics, light is considered to travel in straight lines, while in physical optics, light is considered as an electromagnetic wave. Physical optics is the study of the wave properties of light, which may be roughly grouped into three categories: interference, diffraction, and polarization And In physical optics, light is considered to propagate as a wave. This model predicts phenomena such as interference and diffraction which are not explained by geometric optics. The speed of light waves in air is approximately 3.0×108 m/s (exactly 299,792,458 m/s in vacuum)

Nano-optics is the study of optical phenomena and techniques on the manometer scale, that is, near or beyond the diffraction limit of light. It is an emerging field of study, motivated by the rapid advance of Nano science and nanotechnology which require adequate tools and strategies for fabrication, manipulation and characterization at this scale.In Principles of Nano-Optics the authors provide a comprehensive overview of the theoretical and experimental concepts necessary to understand and work in nano-optics. With a very broad perspective, they cover optical phenomena relevant to the nanoscale across diverse areas ranging from quantum optics to biophysics, introducing and extensively describing all of the significant methods.

Optical Imaging is the method in which light is being used to get the investigational imaging of the medical operations. Basically, optical imaging is of two types which are diffusive Imaging systems and ballistic imaging system. Some of the main examples are scanning laser ophthalmoscopy, optical coherence tomography, optical microscopy and endoscopy, spectroscopy.

Photonics is an area of study that involves the use of radiant energy (such as light), whose fundamental element is the photon. Photonic applications use the photon in the same way that electronic applications use the electron. Devices that run on light have a number of advantages over those that use electricity.Applications of photonics: Applications of photonics are ubiquitous. Included are all areas from everyday life to the most advanced science, e.g. light detection, telecommunications, information processing, photonic computing, lighting, metrology, spectroscopy, holography, medicine (surgery, vision correction, endoscopy, health monitoring), bio photonics, military technology, laser material processing, art diagnostics (involving InfraRed , Reflectography, Xrays, UltraViolet fluorescence, XRF), agriculture, and robotics.

These are the optics which belong to the branch of optics and photonics which uses light controlling components to get the images of the celestial objects in the space. The perfect example for this would be a telescope.

Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometric optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. Three basic laws: The law of rectilinear propagation (transmission). When a ray of light is reflected at an interface dividing two optical media, the reflected ray remains within the plane of incidence, and the angle of reflection θ r equals the angle of incidence θ i.


Basic Principle of Interferometer. Interferometer is a precise instrument for flow visualization. The variation of refractive index of the flowing gas with density is the basic principle used in thses system. The principle of interference of light waves is used.


Laser medicine consists in the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, photo rejuvenation, and laser surgery.While the history of laser begins in 1951, the first medical application is reported by Goldman in 1962. In cardiovascular surgery McGuff first used a Ruby-Laser in 1963 for the experimental ablation of atherosclerotic plaques. After a long time of investigations and new developments in laser technology first clinical applications were performed by Choy and Ginsburg in 1983. Since that time the effectiveness of laser angioplasty in coronary and peripheral vessel is investigated in several clinical trials and first results are encouraging, so that laser is about to find its place in the treatment of cardiovascular diseases too.


Light, like radio, consists of electromagnetic waves. The major difference between the two is that light waves are much shorter than radio waves. The use of electromagnetic waves for long-distance communications was the beginning of an industry known first as wireless and later as radio. This industry was the foundation for electronics, which brought the world so many fascinating technologies.

There are four types which are: solid state, gas, dye, and semiconductor. The characteristics of each type will be described. Solid State Lasers employ a lasing material distributed in a solid matrix. One example is the Neodymium: YAG laser (Nd:YAG).

  • Solid-state laser:   A solid-state laser is a laser that uses solid as a laser medium. In these lasers, glass or crystalline materials are used
  • Gas laser: A gas laser is a laser in which an electric current is discharged through a gas inside the laser medium to produce laser light. In gas lasers, the laser medium is in the gaseous state
  • Liquid laser: A liquid laser is a laser that uses the liquid as laser medium. In liquid lasers, light supplies energy to the laser medium.
  • Semiconductor laser: Semiconductor lasers play an important role in our everyday life. These lasers are very cheap, compact size and consume low power. Semiconductor lasers are also known as laser diodes.

Astrophysics is a science that employs the methods and principles of physics in the study of astronomical objects and phenomena. As one of the founders of the discipline said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–what they are, rather than where they are. Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.

Laser based 3D scanners use a process called trigonometric triangulation to accurately capture a 3D shape as millions of points. Laser scanners work by projecting a laser line or multiple lines onto an object and then capturing its reflection with a single sensor or multiple sensors.

Types of 3D Scanners and 3D Scanning Technologies:

Short Range 3D Scanners Short Range 3D scanners typically utilize a Laser triangulation or Structured Light technology.

Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication systems Fields within organic photonics include the liquid organic dye laser and solid-state organic dye lasers. Materials used in solid-state dye lasers include.

Advantages: Its great advantage is that it can be manufactured just like normal computer chips but with patterned silicon to transmit data-carrying laser signals. Able to carry more data while consuming less power and without heating up or causing any degradation in signal, silicon photonics will disrupt a range of technologies.

Photonic crystals are periodic dielectric structures that are designed to form the energy band structure for photons, which either allows or forbids the propagation of electromagnetic waves of certain frequency ranges, making them ideal for light-harvesting applications (Maka et al., 2003).

Applications:  Photonic crystals are attractive optical materials for controlling and manipulating light flow. One dimensional photonic crystals are already in widespread use, in the form of thin-film optics, with applications from low and high reflection coatings on lenses and mirrors to colour changing paints.

Materials, structures, phenomena and devices that are still in an investigative stage, or that are not yet targeting specific application requirements. Novel materials and material combinations and structures that are enabling new functions or science, and nanophotonic structures. Potential examples include (not limited to) low dimensional structures, amorphous or disordered materials, graphene, complex oxides, photonic crystals, antennas, gratings, subwavelength structures, and plasmonics and their hybrids.
