Multispectral optical performance detector

Abstract

The invention belongs to the technical field of detectors, particularly relates to a multispectral optical performance detector, and provides the following scheme for solving the problems that an existing detector is simple in design structure, a processor in the existing detector is poor in heat dissipation effect in the working process, and the service life of the processor is affected. Themultispectral optical performance detector comprises a shell, an air inlet is formed in the outer wall of the bottom of the shell, a support is fixed to the inner wall of the air inlet through screws, a motor is fixed to the outer wall of the bottom of the support through screws, an output shaft of the motor is connected with fan blades through a coupler, a mounting column is fixed to the inner wall ofthe bottom of the shell through screws, and a circuit board is fixed on the outer wall of the top of the mounting column through screws. Under the action of a V-shaped flow guide plate, hot air and airflow emitted by a processor in a wind shield are subjected to sufficient heat exchange, and the exchanged heat is discharged through inclined holes along vertical holes, so that heat dissipation ofthe interior of the detector is completed, a good heat dissipation effect is achieved, and the service life of the processor in the device is prolonged.

[0002] In recent years, multispectral imaging technology has become an important development direction. However, the corresponding multispectral imaging system technical performance testing device and method have not yet been established. Domestic performance testing devices for multispectral imaging systems are still limited to broadband imaging systems. In terms of comprehensive performance parameter testing, at present, in order to meet different applications under multiple spectral wavelength conditions, it is necessary to include coaxial use of visible light, infrared, and various laser wavelengths, as well as laser transmission and laser receiving systems of different wavelengths. A parallel light performance testing device that satisfies multi-spectrum, has both light transmission and light reception, and is used for multi-spectral optical axis calibration and performance testing

[0003] Detectors are often used in the process of detecting multispectral optical properties. The existing detectors have a simple design and structure, and the internal processor has a poor heat dissipation effect during work, which affects the service life of the processor. Obviously Can no longer meet people's needs
