High-Speed Process Visualization Using Metal Vapor Brightness Amplifiers

摘要

In this paper, we discuss the experimental results obtained using a laser monitor (laser projection microscope) which is used for observing processes through shielding background lighting: interaction of powerful energy with matter, combustion processes (e.g. self-propagating high-temperature synthesis), and plasma-induced processes. The method and equipment for visualization and monitoring of these processes in real-time using single-frame image registration are suggested. The active media of copper bromide vapor lasers with the high pulse repetition frequency (PRF) is considered to be the perfect gain medium for laser monitors. To increase the time resolution of the system and the image quality we suggest the scheme in which the image amplifier and high-speed camera operate synchronously. The prototype of a compact laser monitor is designed. Further development of laser monitors is also discussed.
