According to the spectral distribution of the laser illuminator and reflectance of the scene,the spectral distributions of reflection of dark green paint,rough concrete and green vegetation under the laser radiation were deduced.

The experiment on the performance of LLL night vision instrument for driving with laser illuminator in the field under glimmer night light is summarized.

It is a new type device consisting of laser illuminator system, special optical system and high performance low-level-light intensifier.

The image fusion method of Laplacian pyramid was described and the fusion rule for dual spectral images in space domain was given, Pyramid technique was used to carry out fusion processing study for random instantaneous laser assistant vision image and low light level (LLL) image.

The resolution and reconstruct of the low light level (LLL) image and laser assistant vision image were analyzed using wavelet transform on the basis of the theory of image detection.

In this paper, the theoretical and experimental research is proceeded to investigate the mechanism of laminar premixed combustion by laser-induced excitation of oxygen molecules.
