    vacuum or outer space. When the light passes into a material at an angle‚ the light beam is bent or refracted according to Snell’s Law and the index of refraction of the material. But also‚ the speed of light through a material varies slightly with the wavelength or frequency of the light. Thus‚ each wavelength is refracted at a slightly different angle when passing through a material at an angle. This spreading out of beam of light is called dispersion. Types of Dispersions and ways to reduce: Chromatic

    The field of optics is one of the oldest and most important branches of the sciences. Long before the theory of electromagnetism was developed‚ optical phenomena were studied‚ characterized‚ and used as probes of nature. Since the invention of the laser a half-century ago‚ this tool has become the preeminent source for all studies involving light. It too has revolutionized countless areas of high technology including telecommunications‚ data storage‚ semiconductor manufacturing‚ healthcare technology

    Introduction Laser scanning is a lot like photography. A 3D scanner is a device that analyzes a real-world object or environment to collect data on its shape and possibly its appearance for example colour. The collected data can then be used to construct digital‚ three dimensional (3D) models useful for a wide variety of applications. While a camera collects colour information about surfaces within its field of view‚ 3D scanners collect distance information about surfaces within its field of view
