Abstract

PURPOSE:To detect the rotational displacement of a liquid cell continuously at high velocity by a method wherein ultrasonic pulses emitted into stationary liquid are reflected by several ultrasonic wave reflecting boards arranged in the liquid, transmitted through specified places temporally and spatially and detected by the Fourier optical system outside the cell. CONSTITUTION:An oscillator 2 emitting ultrasonic pulses and two reflecting boards 3a and 3b reflecting these ultrasonic pulses are provided inside the ultrasonic liquid cell 1. In the upper and lower surfaces of the cell 1 are fitted lenses 5 and 6 to transmit parallel luminous flux from a laser beam source 8 into the cell 1 and to image the same at the center of a detecting filter 4, and an optical filter 7 having three rectangular openings is arranged in parallel to these two lenses 5 and 6. The Fourier transform optical system for detecting the ultrasonic pulses is constituted by the laser beam source 8 and a magnifying lens 9 and by the lenses 5 and 6, the detecting filter 4 and a photoelectric transducer 10.
