Abstract :
The paper presents state of the art for laser projection microscopes and their application for monitoring objects and processes hidden from view of an observer by a layer of bright luminous plasma. We show the possibility of registration of an image, which is obtained using laser projection microscope and is formed by a single pulse of the optical amplifier. Laser monitor based on CuBr-laser with a frame-by-frame imaging has been used for the first time. The paper presents the results of visualization of the process of self-propagating high-temperature synthesis, which is attended by intense stray lighting in real-time mode using synchronizing system of an optical amplifier and a high-speed camera.
