Abstract:
The paper presents the results of quality assessment of images made using a copper bromide vapor laser monitor. Two different imaging techniques were used for the study: laser illumination and amplification using laser active medium (so called laser monitor). The images were numerically evaluated using the following informative parameters: standard error, Shannon entropy (H), and zero mean normalized cross-correlation (ZNCC). It is shown that use of an active medium introduces into images small distortions, which depend on the stability of amplification properties of the active medium. In the scheme of laser illumination, the influence of instability is less pronounced. The imaging in single-frame mode can decrease the distortions introduced by the active medium.
