摘要：
We present results of using a laser monitor with an independent illumination source (bistatic laser monitor) for imaging processes blocked from an observer by the background light. The maximal imaging speed was 15 x 10(3) fps. The possibility to observe the structural transformations in a combustion wave of self-propagating high-temperature synthesis is shown. A bistatic laser monitor is shown to allow significant improvement of the image quality (contrast and brightness) of low-contrast objects.
