Abstract

PURPOSE:To measure the distance and speed simultaneously in the same optical system, by detecting the distance and speed with separate beam splitters and photo detectors when an interfering lights are reflected back from the surface of an object to be measured passing through two beam splitters. CONSTITUTION:A semiconductor laser light source 1 with the oscillation wave length stabilized is modulated in the pulse and intensity with a driving section 2. A modulated light 4 turned to a parallel beam with a lens 3 is reflected on the surface of an object 6 to be measured passing through beam splitters 5 and 5'. When reflected, light of an oscillation frequency f0 undergoes a Doppler shift based on the motion of the object being measured and is returned as reflected light with the oscillation frequency of f0+DELTAf. A decision circuit section 9 judges the time lag or the like of the reflection pulse light to calculate the distance of the object being measured. On the other hand, the difference DELTAf between the frequencies f0 and f0+f made incident as reflected with a mirror 10 is detected with a detection circuit section 11 to find the speed of the object being measured.
