Imaging by means of the bistatic laser monitor

Abstract

The intensive development of beam, plasma, discharge and laser technologies makes non-destructive testing methods and devices based on passive and active optical systems. There is an active optical system, which is called a laser monitor. The using of this system makes it possible to form images of test objects and processes suitable for analysis even under background radiation, however, the imaging distance does not exceed 3.3 m. The bistatic scheme of the laser monitor is designed to expand the capabilities of imaging using active media on metal vapors. This paper shows the operation features of the bistatic laser monitor as well as the parameters of the formed images. One of the issue is to compare the amplification of image brightness in an optical converter due to the different laser monitor scheme modification.
