Photoelectric load multi-optical-axis space angle precision calibrating device

The utility model discloses a photoelectric load multi-optical-axis space angle precision calibrating device capable of performing high-precision measurement on a space angle of an optical axis. According to the calibrating device (1), a high-stability measuring bracket (4), a high-precision right-angle prism azimuth monitoring device (7) and a high-precision two-dimensional straight line working table (8) are directly arranged on a high-stability supporting platform (2). An azimuth pitching fine adjustment mechanism (5) with an optical reference mirror (6) is arranged on the high-stability measuring bracket (4). The high-precision right-angle prism azimuth monitoring device (7) and the high-precision two-dimensional straight line working table (8) are arranged on a straight line. A high-precision auto-collimation digital theodolite (9) and electronic level meters (10) are arranged on the high-precision two-dimensional straight line working table (8), wherein two electronic level meters (10) are perpendicular to each other. The high-precision auto-collimation digital theodolite (9) and the electronic level meters (10) are connected with a computer data acquisition and processing system (11).
