摘要

1. The use of a single-frequency semiconductor laser with a wavelength of 1064 nm and a generation line width of not more than 3 MHz as a reference source of radiation from a laser speed meter and / or moving small objects in places with limited access. 2. A laser meter for the speed and / or movement of small objects in places with limited access, including a single-frequency semiconductor laser with a wavelength of 1064 nm and a generation line width of no more than 3 MHz, an optical isolator, a fiber amplifier with a laser pump diode, an optical radiation divider that performs the function of a beam splitter plates, to which a connector with an angled cleavage is connected, which performs the function of a low-reflecting mirror, a collimator with a beam diameter of 0.8-1.2 mm, and an optical receiver, the output of which is connected en to the input of the oscilloscope connected via USB-interface kompyuterom.3. The laser meter according to claim 2, characterized in that the optical radiation divider is configured to divide radiation 1: 1.
