Problems solved by technology
The optical device used in this laser beam diagnostic system has a complex structure, and it is easy to generate additional beam distortion; moreover, as the power / energy of the measured laser beam increases, the distortion will also increase, which makes the final laser beam characteristics Large deviation from actual characteristics
Therefore, the existing laser beam diagnostic system is only suitable for the diagnosis of small power / energy, small diameter or near-field beam, not suitable for large beam diameter, extra large beam diameter, far-field or high power / energy beam diagnosis

Embodiment Construction
[0033] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment.
[0034] The invention proposes a diffuse target with Lambertian properties, which is formed by combining a diffuse layer on a substrate. According to the difference of the diffusing layer and the substrate combined with it, the diffusing target can be divided into a diffuse reflection target and a diffuse transmission target.
[0035] Referring to Fig. 1, it is a structural diagram of a diffuse reflection target with Lambertian properties proposed by the present invention. The diffuse reflection target 1 includes a diffuse reflection layer 11 and a substrate 12, which are combined by high-temperature spraying. The diffuse reflection layer is a particle The particle size is the same order of magnitude as the measured laser wavelength. In order to be able to measure strong laser light, the melting point of the granular material in the diffuse reflection la...

The present invention is diffusion target, laser beam diagnosis system with the diffusion target and its diagnosis method. The diffusion target includes base and diffusion reflecting layer set on the surface of the base or inside the base. The laser beam diagnosis system with the diffusion target includes diffusion target with Lambert characteristic, CCD imaging module, and datan acquiring and processing device, with the diffusion target being diffusion reflecting target or diffusion transmitting target. The diagnosis method includes: for the diffusion target to diffuse the tested laser beam into diffusion laser, for the CCD imaging module to receive the diffused laser, image and output image data to the datan acquiring and processing device, and for the datan acquiring and processing device to process the datan and to obtain characteristic datan of laser beam. The present invention is precise and is especially suitable for large diameter laser beam diagnosis.
Description
technical field [0001] The present invention relates to a diffuse target and a laser beam diagnosis system using the diffuse target and its diagnosis method, especially a laser beam diagnosis system and its diagnosis method using diffuse light imaging of a diffuse target, belonging to the information field of science and technology. Background technique [0002] Existing laser beam diagnostic systems generally include a specific optical device for reducing the diameter of the measured laser beam to less than the size of the CCD target surface, and also include: CCD imaging devices, data acquisition and processing devices, the The specific optical device can reduce the diameter of the measured laser beam to be smaller than the size of the CCD target surface, and then use the CCD imaging device to receive and measure it, and the measurement results are output to the data acquisition and processing device. The signal measured by the CCD imaging device is collected and processe...
