About This Special Issue
Optical engineering is the engineering discipline that focuses on the design of equipment and devices that function by using light. It is based on the science of optics, a field of physics that studies the properties and behaviors of visible light and its two nearest neighbors on the electromagnetic spectrum, infrared and ultraviolet. In modern times, this field is important to a very wide array of technologies, including optical instruments such as microscopes and binoculars, lasers, and many commonly used electronic and communication devices. Some practical applications of optics can be done using a model of electromagnetic radiation based on classical physics. Optical engineering is likewise essential to fiber-optic technology, which transmits information through cables using pulses of light instead of electricity. This special issue is designed to provide a view into the current state-of-the-art techniques in optical engineering and advanced applications of optical technologies.
