Abstract

The invention discloses a photoelectric detection device applied to gyroscope position monitoring, and belongs to the technical field of product structures for monitoring gyroscope positions through photoelectric detection devices and methods. The photoelectric detection device comprises a gyrosphere and an outer sphere. The surface of the outer sphere is tightly connected with a first photoelectric position detector and a second photoelectric position detector which are orthogonal to each other; the inner surface of the gyrosphere is tightly connected with at least one pair of orthogonal laser diode components; and the photoelectric position detectors are electrically connected with a processing module through signal output cables. By the structure, a problem that the angle detection accuracy is reduced due to influence of temperature and the movement of the outer sphere can be solved in the process of monitoring a gyroscope angular position, and the defects of high power consumption, large interference, existence of interfering moment, low dynamic accuracy, large temperature shift, untimely response and the like when the gyroscope angular position is monitored in the prior art are overcome.
