ABSTRACT:
A system for measuring the motion amount of laboratory animals includes a main body having a single central processing unit installed, a single frame set to surround an animal in a bounded area, optical sensor light-emitting elements and optical sensor light-receiving elements disposed on opposite sides of the frame. The optical sensor light-emitting elements sequentially emit optical beams such that the light-emitting elements do not simultaneously emit optical beams, the optical beams being received by corresponding light-receiving elements when the emitted optical beams are not obstructed so as to detect the location and movements of the laboratory animal.
