Remote laser measurement device of rotating speed of rotary objects

The utility model provides a remote laser measurement device of rotating speed of rotary objects. The remote laser measurement device can measure the rotating speed of the rotary objects remotely in non-contact mode, and therefore measurement devices and operating personnel can keep far away from measured objects to be safe and reliable, and measurement results are accurate and visualized. The remote laser measurement device has the advantages of being small in size, convenient to carry, simple to operate and the like. The remote laser measurement device comprises a remote laser rotating speed sensor fixed on a support, a counting device connected with the remote laser rotating speed sensor, and a reflective film attached on the rotary objects. The remote laser rotating speed sensor comprises a laser generator and a twin lens assembly composed of a laser light-emitting lens and a scattered-light focusing lens, wherein the laser generator sends laser beams through the laser light-emitting lens and recovers las
