Photometer
A photometer is an instrument used to measure the intensity of light. In the context of space and astronautical engineering, photometers are used to measure the brightness of celestial objects such as stars, planets, and galaxies. They are often used in telescopes and other space-based observatories to study the properties of these objects, such as their temperature, composition, and distance from Earth. Photometers can also be used to detect and measure the intensity of light emitted by spacecraft and other man-made objects in space. This information can be used to monitor the health and performance of these objects, as well as to study the effects of space radiation and other environmental factors on their operation.
