Problems solved by technology
[0003] The multi-spectral LED light path is for splitting and synthesizing imaging of LED light. LED light contains less infrared light. If the infrared light is strong, it needs to be separated and imaged. Since the separation of visible light and infrared light and wind needs to work together with detection equipment, if If the infrared light is weak, the spectroscopic operation can be omitted, and the use of infrared light detection equipment can be saved, but the current equipment is not convenient to separate the control according to the specific infrared light intensity, and the overall operation is more troublesome. Therefore, it is necessary to provide a A new imaging-based multi-spectral LED optical path synthesis device solves the above technical problems

The invention discloses an imaging-based multi-spectrum LED optical path synthesis device, which comprises a packaging case, a light entering cylinder and a light exiting cylinder, the light entering cylinder is fixed at one end of the packaging case, and the light exiting cylinder is fixed at a part of the packaging case away from the light entering cylinder One side also includes: a plane grating, a front reflector, a front light mirror, a rear reflector, a long-moving mirror and a light-condensing sheet, the planar grating package is fixed in the package, and the planar grating is aligned with the light entrance tube, The front reflector is fixed inside the package and located above the plane grating. This imaging-based multi-spectral LED optical path synthesis device separates the infrared light, so that the visible light is concentrated and transmitted for imaging. According to the influence of the intensity of the infrared light on the imaging , can selectively adjust the reflective part to separate and emit stronger infrared light, and cooperate with the use of the detector to restore imaging. When the infrared light is weak, no separation is required, which saves the use of external equipment and simplifies the imaging operation.
Description
technical field [0001] The invention relates to the technical field of multispectral synthesis, in particular to an imaging-based multispectral LED optical path synthesis device. Background technique [0002] Spectral imaging technology is to divide the incident full-band or wide-band light signal into several narrow-band light beams, and then image them on the corresponding detectors to obtain images of different spectral bands. [0003] The multi-spectral LED light path is for the split synthesis imaging of LED light. The LED light contains less infrared light. If the infrared light is strong, it needs to be separated for imaging. Since the separation of visible light and infrared light and wind needs to work together with the detection equipment, if If the infrared light is weak, the spectroscopic operation can be omitted and the use of infrared light detection equipment can be saved. However, the current equipment is not convenient to control the separation according to ...
