The utility model belongs to the technical field of sensors, and particularly relates to a reflection type laser displacement sensor, which comprises a shell, an optical fiber collimator arranged on the shell, a grating window movably arranged in the shell, a reflector arranged on the grating window, and the optical fiber collimator right facing the grating window. According to the utility model, the reflector is arranged on the grating window, and the reflector can move relatively along with the movement or rotation of the grating window so as to modulate the laser emitted by the optical fiber collimator, and the modulated laser information is reflected back along the original path through the reflection of the reflector. 本实用新型属于传感器技术领域，具体涉及一种反射式激光位移传感器，包括壳体，在所述壳体上设置有光纤准直器，在所述壳体内活动设置有光栅窗，在所述光栅窗上设置有反射镜，所述光纤准直器正对光栅窗设置。本实用新型将反射镜设置在光栅窗上，反射镜可随光栅窗的移动或者旋转进行相对运动，进而对光纤准直器发出的激光进行调制，并通过反射镜的反射将调制激光信息原路反射回去。
