ACOUSTIC-AND-OPTICAL METHOD DETERMINATION OF DISTANCE TO OBJECT Russian patent published in 1994 - IPC

Abstract RU 2020409 C1

FIELD: measurement techniques. SUBSTANCE: method is based on use of acoustic-and-optical transducer controlled by feedback with signal formed from frequency jump in heterodyne interaction of component of monochromatic coherent radiation passed through said transducer. One of components is reflected from object. EFFECT: extended range of distances due to application of acoustic-and-optical transducer. 2 dwg
