“…These imaging systems allow observation through the flame or plasma and visualization of the processes shielded by intensive background lighting. In particular, they can be used to perform diagnosis of the substance surface burning with high intensity of light emission during the combustion or plasma induced processes [10][11][12][27][28][29][30]. For the first time, an active optical system with brightness amplification was used to study the aluminum nanopowder combustion in [12].…”

The paper discusses the application of laser illumination and brightness amplification techniques for studying the process of high-temperature combustion of aluminum and iron nanopowders and their mixtures. The laser equipment for visualization based on solid-state laser illuminator, brightness amplifier on copper bromide vapors and high-speed camera is considered. These approaches allow the increase of monitoring distance to 50 cm, which is important for high-temperature processes imaging. The video images allow studying the surface morphology changes during high-temperature combustion identifying the main stages of combustion, spreading of the heat waves and cooling.

“…The use of active optical systems with brightness amplifiers allows to monitor such processes. [1][2][3][4][5][6][7][8][9] "Looking through the flame" becomes possible due to the high spectral brightness of the active media of metal vapor lasers on self-terminating transitions: 10 the medium serves as an amplifier in a narrow spectral range, or a "nanofilter," which allows to visualize the processes shielded by the wideband background lighting.…”

“…Optical systems with brightness amplifiers used for monitoring objects and processes shielded by the intensive background lighting in a real-time mode are referred to as laser monitors. 5 When using real-time monitoring, a process can be viewed in its course due to the high time resolution. Metal vapor laser media, with high pulse repetition frequencies (PRF) [13][14][15][16][17] and modern high-speed cameras can be used for designing modern high-speed laser monitors.…”

A single-pulse imaging laser projection system (laser monitor) is proposed for real-time monitoring high-speed processes shielded by the intensive background lighting. The brightness temperature of the lighting can reach thousands or even tens of thousands of degrees, which makes it difficult to observe the processes with the naked eye. The estimates of limiting temperatures show that the use of the proposed instrument allows to view the objects when the equivalent brightness temperature of the background lighting is up to 45,000 K. The results of visualization of some bright objects and processes using high-speed copper bromide vapor laser monitor are presented.

“…As it has been already mentioned in a number of previous works, the visualization of fast processes blocked by the broadband background radiation is possible with the use of systems with brightness amplifiers based on metal vapors [2][3][4] and their halides [5,6]. The use of such systems -laser monitors -allows to perform high speed video recording of processes, while the time resolution is specified by a video recorder and a brightness amplifier.…”

In this paper the design of high speed brightness amplifiers on transitions of copper and manganese atoms is discussed. A possibility of obtaining images in active optical systems with a brightness amplifier operating at 100 kHz frequency is demonstrated. The results of comparing the images obtained using brightness amplifiers on copper bromide and manganese bromide vapors are given.Index terms -Laser projection microscope, CVL, high-speed imaging, high pulse repetition rate.
