Range Finding Lasers Overview
Laser range finding is a term used to describe the process of determining the distance to a fixed object. This process is essentially a simplified version of laser radar, and therefore has many of the same requirements as lidar lasers. Since we are only considering stationary targets and distance is the only thing being measured, range finding lasers are always pulsed to measure the roundtrip time-of-flight and calculate the distance to the target. An additional constraint on laser range finding is that not all lidar systems have is the need to be very careful about eye safety since they are typically operating over shorter distances and in more populated areas. As a result, most of these lasers operate around 1.5 microns in wavelength, which is considered to be eye-safe because of the extremely high-water absorption. On this page, you will see a list of all of the range-finding lasers including both passively and actively q-switched Er: Glass lasers.
