Abstract

PURPOSE: To enable mounting to be readily done by providing connectors for optical fibers at the portions where the input light and output light to and from the light polarizing medium of a case having an ultrasonic light modulating element in the inside go in and out respectively.
CONSTITUTION: An ultrasonic light modulating element 1 is constituted by a light deflecting medium 12 composed of ultrasonic light modulating material, a transducer 3 composed of piezoelectric material and a sound absorber 4 and is held fixed to the central part of a case 11. Optical connectors 14 and 15 respectively connecting to optical fibers 12 and 13 are provided to the portions of the case 11 where beam light goes in and out. The input light from the optical fiber 12 is deflected by the ultrasonic light polarizing medium 2 and is outputted into the optical fiber 13 but the fibers 12, 13 are freely flexible and therefore the optical mechanism can be in any construction and disposition, thus this mounting is easy and there is no need for making the optical system complex.
