Abstract: The present invention relates to an optical alignment device of a LIDAR system including a telescope, a laser, a beam separator, a pin hole, a collimating lens, and an oil film reflector. The telescope includes first and second mirrors and is installed in the lower side of a frame. The laser is installed on the rear side of the telescope and irradiates the telescope with laser light. The beam separator is installed on the front side of the telescope and divides the laser light into two beams. The pin hole is installed between the bema separator and the telescope and forms a focus of the laser light. The collimating lens is installed between the pin hole and the beam separator and makes the laser light passing through the pin hole with parallel light and collects the laser light returned. The oil film reflector reflects the laser light passing through the beam separator. According to the composition, an optical system is easily accurately aligned without a disassembly work of the optical system for inspecting the optical alignment during observation or when the optical system for the atmospheric observation is installed. Accurate optical alignment between channels can be formed in a short time regardless of the number of channels of an optical reception terminal.
