Title: Pulse system device for measuring distance by light wave
Inventor: OISHI MASAHIRO
IPC: G01S17/14
Filed: 1988-12-30
Abstract: PURPOSE:To reduce the influence of electric drift by providing a photodetection part which photodetects light beams from a light source part through an internal and an external optical path and at all times and generates one output signal. CONSTITUTION:Light pulses which are emitted by a laser diode 1 are collimated by a lens into parallel luminous flux, which is split by a beam splitter 5 into two pieces of luminous flux. The luminous flux which is reflected by this beam splitter 5 is converged by a lens 3 to travels in the optical fiber 6 for the internal optical path. Namely, the internal reference optical path where the light pulses pass through the optical fiber 6 for the internal optical path and are photodetected by a light receiving element 7 is constituted. Then the light pulses are converted by the light receiving element 7 into an electric signal. The luminous flux passing through the beam splitter 5, on the other hand, is converged by a lens 4 to pass through an optical fiber 8. This delayed luminous flux is reflected by a prism 4, passed through a lens 10, and emitted from the light wave measuring distance device main body. Then the light which is reflected by a corner cube 11 arranged at a measurement position forms an external distance measurement optical path and is converted by the light receiving element 7 into the electric signal.
