Abstract

The invention relates to a multispectral composite optical system based on an electric power complex background, which is used for overcoming the defects that the radial size of the system in the prior art is too large and miniaturization is not facilitated. The device comprises a first detector, a spectroscope, a main reflector group and a second detector which are sequentially arranged along anoptical axis; the main reflector group is used for reflecting incident light to the first surface of the spectroscope; wherein the first surface of the spectroscope can reflect infrared light and transmit visible light, so that the visible light is transmitted into the first lens group and then received by the first detector, and the infrared light is reflected into the second lens group and thenis received by the second detector. The system is suitable for miniaturized power system detection equipment.

Description

Technical field[0001]The invention relates to the field of infrared / visible light common-aperture optical systems, in particular to a multi-spectral composite optical system based on a complex background of electric power.Background technique[0002]The detection environment of the power system is relatively complicated. Generally, it is necessary to detect through the dual band of visible light and infrared light to accurately identify problems such as abnormal cable temperature and cable damage. The power system detection also requires a small volume of the detection equipment, so the power system detection often adopts multi-mode common-caliber composite technology. Commonly used multi-mode common-aperture technology in optics mainly has three structural forms, namely reflection, catadioptric and refraction. Reflective systems are generally large in size and difficult to process and adjust. In addition, if a coaxial reflection system is used, it will be obstructed, while the use of...
