👉 A chromometer is a type of optical instrument used in radar systems to measure the intensity of light. It consists of a series of lenses and mirrors that are arranged in a way that allows the light from a source to pass through one mirror, bounce off another, and then return to the first mirror. The intensity of the light that passes through each mirror is proportional to the square root of the distance between them. This principle is used in radar systems to measure the distance between objects or vehicles using multiple
