Abstract

The application relates to the technical field of optical detection, and particularly to a passive self-collimation parallelism calibration platform and system, and the calibration platform comprisesa substrate provided with a transflective lens module for reflecting parallel light, wherein the transflective lens module is internally provided with a transflective reflector at a 45-degree angle tothe substrate, one side of the transflective lens module is provided with an image forming module arranged opposite to the transflective reflector to allow the entrance of the reflected parallel light, and the bottom of the transflective lens module is provided with a fully reflecting surface on the lower side of the transflective reflector; the calibration system comprises parallel light tubes for emitting parallel light, and also comprises the passive self-collimation parallelism calibration platform described above. The application uses a high-resolution image sensor, receives a test chartand transmits images through a prism plane, determines the inclination angle of the chart through software calculation, and displays the inclination angle data in real time combined with the softwarefor verticality adjustment, so that the calibration is more reliable.

Description

【Technical field】 [0001] The present application relates to the technical field of optical detection, in particular to a passive self-collimation parallelism calibration platform and a calibration system. 【Background technique】 [0002] At present, there is no instrument in the field of collimator to receive the test chart to calibrate the parallelism. The traditional way to judge the parallelism is mainly to use the autocollimator or level to adjust. However, the above two methods are used to judge the test chart. There are the following disadvantages in parallelism: 1. The volume of the autocollimator is too large, and the available adjustment equipment is limited; 2. The adjustment accuracy of the level meter is limited, and there is no detection data. 【Content of invention】 [0003] In order to solve the problem that there is no instrument for receiving test charts for parallelism calibration in the existing collimator field, this application provides a passive self-co...
