Title: Optical fiber speedometer
Inventor: KOYAMA JIROU
IPC: G01S17/58
Filed: 1982-09-13
Abstract: PURPOSE:To eliminate an isolator because laser beam is not passed through a polarizing beam splitter and is not fed back to a laser beam source and to enable the use of semiconductor laser and miniaturization, by imparting reference beam and signal beam to a photoelectric converter while reflecting both beams by the polarizing beam splitter. CONSTITUTION:When an object 6 to be measured is moved in a region to be measured at a certain speed as shown by the drawing, emitted laser beam is again applied to a 1/4 wavelength plate 12 by the object 6. Because reflected laser beam (signal beam) receives doppler shift DELTAf proportional to the speed of the object 6, the frequency of the signal beam comes to fo+DELTAf. Reference beam and signal beam are propagated to reverse directions in an optical fiber 11 but the polarizing direction of laser beam is held and condensed by a lens 4 to be again imparted to a polarizing beam splitter 3. Heterodyne detection due to the beam beats of reference beam and signal beam is performed in a photoelectric converter 7 and an electric signal with frequency of DELTAf. The frequency DELTAf is measured by a frequency measuring instrument 8 and speed information can be obtained in a signal treating part 9.
