optical engineering

Optical engineering is a field that deals with the creation and propagation of light, as well as its interactions and associated phenomena. It encompasses two main branches: physical optics, which explores the nature of light itself, and geometrical optics, which focuses on how lenses, mirrors, and other devices manipulate light to form images.1

Optical engineering also involves optical data processing, where information within an image is manipulated using coherent optical systems. The principles of optics have expanded beyond visible light to include other parts of the electromagnetic spectrum, such as X-rays and infrared radiation. Optical systems are composed of various elements like lenses, mirrors, and detectors, which can include the human eye, photographic film, or electronic devices sensitive to different wavelengths of light. The field has also seen advancements through the integration of communication and information theory, particularly with the development of the laser.1234
