Two dimensional dynamic digital display auto-collimation instrument

The utility model belongs to the technical field of optical detection, which is suitable for a digital display auto-collimation instrument for measuring two-dimensional displacement at the same time. The utility model can change a cross-shaped graticule of the existing one-dimensional auto-collimation instrument into a trigonal graticule. A spectroscope is arranged between a semipermeable membrane cubic prism and a double-reticle graticule, and a CCD receiver is arranged on the reflection image point of the spectroscope and is connected with an electronic measuring device. The control and data processing of the information of the CCD receiver can be carried out by the electronic measuring device. Due to the adoption of the trigonal graticule and the one-dimensional CCD receiver, measuring accuracy can be increased, the structure of the utility model can be simplified, and measuring response speed is quick. The utility model has the advantages of simple structure, low cost, easy implementation, etc.
