The invention provides a multifunctional optical-axis parallelism rectifying instrument and a method for calibrating the rectifying instrument, which can greatly reduce the manufacturing and mounting cost of rectifying equipment and perform flexible configuration to be suitable for the requirements of different multi-optical axis systems to be rectified. The multifunctional optical-axis parallelism rectifying instrument comprises a plurality of discrete parallel light tubes, wherein the plurality of parallel light tubes are in one-to-one correspondence with a plurality of sub-systems of the multi-optical axis system to be rectified; and the plurality of parallel light tubes are fixedly mounted on a compound table respectively through a positioning block, and a fine adjustment-locking device is arranged in the positioning block. The multifunctional optical-axis parallelism rectifying instrument provided by the invention can avoid the processing risk and high cost of a large-caliber non-spherical reflecting mirror and can meet the requirements of large optical axis span parallelism rectification; and a targeted light source and observation equipment can be adopted, thus functional modules do not need to be replaced during the rectification process, the operation is simple and ordered, and the repeated adjustment is not required.

Description

technical field [0001] The invention relates to an optical correction device and a calibration method thereof, and mainly relates to detection and correction of optical axis parallelism of a multi-optical axis optical system to be corrected. Background technique [0002] The traditional method for measuring the parallelism of the optical axis is to use a large-diameter off-axis parabolic reflective collimator. In order to detect the parallelism of multiple optical axes, the effective aperture of the collimator must cover the optical system under test. When detecting the parallelism of the optical axis of the optical aiming and tracking system, the parallel light emitted from the focal plane should be imaged in the transmitting system, receiving system and aiming system at the same time. [0003] In order to avoid blocking the optical path, a parabolic structure is required to keep the focus away from the optical axis. [0004] At the same time, it is necessary to adopt a r...
