The invention belongs to the technology of reflector online detection and particularly relates to a universal type online measuring device for laser gyroscope reflectors. The universal type online measuring device comprises a laser gyroscope cavity, optical cement cushion blocks, reflection reduction mirrors and sealing reflectors. The laser gyroscope cavity comprises a cathode, an anode, gas storage holes and capillary pores. The two optical cement cushion blocks are symmetrically arranged on the two sides of a certain gas storage hole to be measured, internal through holes of the optical cement cushion blocks are communicated with the gas storage hole to be measured through inclined through holes, the reflection reduction mirrors are arranged on optical cement surfaces perpendicular to the internal through holes of the optical cement cushion blocks, and the sealing reflectors are arranged on the rest of the gas storage holes. When the device carries out measurement, a testing laser passes through the reflection reduction mirrors, the inclined through holes and the reflector to be detected on one side and the inclined through hole and the reflection reduction mirrors on the other side in sequence, the information of the exit laser is detected in real time, and the real-time change of the performance of the reflector to be measured can be obtained. The device can effectively relieve the influence of plasma on the performance of the reflection reduction mirrors and ensure the accuracy of measurement results, makes high-precision optical processing easy and is high in universality.
