Abstract:
1. An optical signal transmission structure of a laser distance measuring device, comprising: a laser pipe, suspended statically and directly above a center of a rotation disk, to emit laser beam; a light projector module, provided with at least two reflection plates, to project laser beam of said laser pipe onto a target; a lens, disposed on said rotation disk, to receive laser beam reflected from said target; and a circuit board, disposed statically in a position opposite to that of said rotation disk, laser beam received by said lens is irradiated onto a light sensor element on said circuit board, to produce at least a photoelectric signal, so that circuits on said circuit board determine distance to said target based on said at least a photoelectric signal, wherein laser beam emitted by said laser pipe is irradiated onto a center of said rotation disk in rotation, and wherein a principal axis of said lens intercepts a vertical dotted line through center of said rotation disk.
