The invention discloses a multiple laser emission optical axis adjustment device based on a tracking detector and a method. The device comprises a laser with the wavelength of lambda 1, a laser with the wavelength of lambda 2, a reflection mirror, a first electric adjustment mirror, a second electric adjustment mirror, a beam splitter, a backward reflection mirror and the tracking detector. Laser lambda 1 emitted by the laser with the wavelength of lambda 1 can be reflected to the first electric adjustment mirror through the reflection mirror. Laser lambda 2 emitted by the laser with the wavelength of lambda 2 can be transmitted by the first electric adjustment mirror. Through the first electric adjustment mirror, two laser optical axes coincide. Laser after beam combining is reflected to the beam splitter through the second electric adjustment mirror. According to the laser after beam combining, a part of the laser is transmitted to the backward reflection mirror, and the other part of the laser is reflected into the tracking detector. According to the invention, existing devices in a photovoltaic system are used to realize automatic adjustment of multiple laser emission optical axes, and the capacity of rapid deployment of the photovoltaic system is improved.
Description
technical field [0001] The invention relates to the technical field of precision optical axis adjustment in photoelectric systems, in particular to a multi-channel laser emission optical axis adjustment device and method based on a tracking detector. Background technique [0002] The existing precision optical axis adjustment technology mostly uses specially designed devices to realize the measurement and adjustment of the consistency of multiple optical axes of the photoelectric system. In applications that require rapid arming of the photoelectric system, this method is difficult to meet the speed and convenience of optical axis adjustment. Especially when the application environment of the system is complex and changeable, the mechanical vibration is widespread, and the temperature changes frequently, it is even more necessary for the photoelectric system to be able to easily adjust the optical axis in a short time. Contents of the invention [0003] The invention over...
