Optics, the science concerned with the origin and propagation of light, its transformation and production, and other phenomena are closely associated with it. There are two major branches of optics, physical and geometric. Physical optics is primarily concerned with the nature and properties of light itself. Geometrical optics deals with the principles that govern the image-forming properties of lenses, mirrors, and other devices that use light. It also includes optical data processing, which involves manipulating the information content of an image created by a coherent optical system.

Originally, the term optics was only used in relation to the eye and vision.

Later, lenses and other devices began to be developed to aid vision, these were inherently called optical instruments, and the meaning of the term optics eventually expanded to cover any application of light, even if the last The receiver is not the eye, but a physical detector, such as a photographic plate or television camera. In the 20th century, optical methods began to be widely applied to regions of the electromagnetic radiation spectrum that were not visible to the eye, such as X-rays, ultraviolet, infrared, and microwave radio waves, and to the extent that these areas are often right now. involve. General field of optics. The present article considers the image-forming properties of lenses, mirrors and other devices that use light. The wave and quantum nature of light, its velocity, wavelength, polarization, diffraction, and interference can be found in light. Many companies selects the best optical lenses manufacturer from the list of custom optical prism manufacturer which uses precision optics manufacturing process to manufacture optics. The analysis of light into its constituent colors by prisms and gratings forms the basis of the broad field of spectroscopy, the principles of which are discussed in spectroscopy. For information about the reception of light by the retina of the eye and the interpretation of images by the brain, see Eye, human.

Optical Image

An optical image can be thought of as the apparent reproduction of an object by a lens or mirror system, employing light as a carrier. A complete image is usually generated simultaneously, as by a lens in a camera, but images can also be generated sequentially by point-by-point scanning, as in a television system or over long distances in space. . . In the radio transmission of pictures. Nevertheless, the final detector of all images is always the human eye, and, whatever means is used to transmit and control the light, the final image must either be produced simultaneously or scanned so rapidly. needed. the wanted. Whether the persistence of the observer’s vision gives him the impression of a complete image covering the limited field of mental vision.
