Analysis and verification
The main parameters that affect ranging ability are peak power of lasers, divergence angle, transmitting and receiving transmittance, wavelength of laser, etc.
For this laser rangefinder, it takes≥70kw peak power of lasers, 0.3mrad divergence angle, 1535nm wavelength, transmitting transmittance≥90%, receiving transmittance≥80% and 47mm receiving aperture.
It is a laser rangefinder for small targets, ranging ability can be calculated by the following formula. Ranging formula for small targets：
As long as detectable optical power that reflected by targets is larger than minimum detectable power, a laser rangefinder is able to range distance to a target. For a laser rangefinder with 1535nm wavelength, generally, the minimum detectable power(M.D.S) of APD is 5×10-9W.
Under 12km visibility with 12km distance to targets, the minimum detectable power is lower than M.D.S of APD(5×10-9W), therefore, under a condition with 12km visibility, a laser rangefinder can range distance for (2.3m×2.3m) targets up to 11~12km(might be close or less than 12km).
