laser-based detection

Laser-based detection uses focused laser beams to identify and measure objects or substances accurately. The laser sends out a narrow, intense light that reflects off surfaces or interacts with particles. By analyzing the reflected light or the change in the laser beam (such as how it scatters or shifts in frequency), sensors can determine the presence, distance, size, shape, or composition of the target. This technology is used in various fields, including medical imaging, environmental monitoring, and security, because it provides precise, rapid, and remote detection capabilities without physical contact.
