Laser rangefinders HIGH range resolution

摘要

The invention relates to an optical instrument engineering, namely - to the technical means to measure the distance of objects in the terrain using laser radiation, and can be used in optical observation devices, rangefinder sight and other devices. Laser range with high resolution in range comprises transmitting, receiving and phase channels in which the set transmission channel respectively lens receiving channel lens and the lens phase channel as well as pulsed semiconductor laser, a photodiode, forming a current pulse circuit, the pulse generator, a receiver, control circuit and information processing, the radiation pulse sensor, a display, a semiconductor laser frequency, modulation frequency generator, power frequency signals and measuring circuit phases. Switching semiconductor laser with a lens mounted sequentially transmitting channel, a photodiode is mounted in series with a lens receiving channel, and the frequency semiconductor laser is mounted in series with the lens phase channel. The technical result - the creation of a laser rangefinder with a higher resolution in range, which provides a distance measurement up to a few kilometers with increments of not more than one meter, and in the range of distances up to several hundred meters - increments not exceeding a few centimeters, and also capable of measuring the minimum distance of the order of fractions m. 1 yl.
