light detection
Noticing brightness presence
Light detection is the process of sensing or measuring light, whether by biological systems like eyes or technological instruments like sensors and photodetectors.
The term appears in technical contexts involving cameras, fiber optics, and remote sensing.
LIDAR (light detection and ranging) uses laser pulses to measure distances and map terrain.
