IMPROVEMENTS IN THE REGULATION OF THE OPTOMECANIC RECEIVING SYSTEM OF A LIDAR CEILOMETER.

摘要

Improvements in the regulation of the optomechanical receiver system of a lidar ceilometer. Optomechanical receiver system of a lidar ceilometer (laser radar for measurement of cloud height) that includes a set of optical elements that focus the laser energy back scattered by the clouds towards the surface of that photodetector that is desired to be coupled to its output. The optomechanical system also has a diaphragm (spatial filter) adjustable in alignment that allows to reduce the noise of the received signal, as well as two devices for regulating the equivalent focal distance of the system. This achieves a significant increase in the maximum range of the ceilometer along with significant improvements in the measurement range of the instrument. This invention can be applied industrially as part of lidar ceilometers as well as in any other type of laser radar that requires said benefits.
