Abstract

PURPOSE: To enable the easy angle adjustment of incident light by the constitution comprising providing an ultrasonic wave medium in contact with the surface of a curved piezoelectric element.
CONSTITUTION: For example, a piezoelectric element 5 comprising providing electrode films 4, 4' on both surfaces of a piezoelectric material 3 is affixed to a curved substrate part 2 and an ultrasonic wave medium such as of water is filled in the spacing 8 in the upper part of the piezoelectric element 5. When a high frequency is inputted to the piezoelectric element 5 from a high frequency power source 6, condensation and rarefaction waves maintaining an equal spacing from the curved surface are generated in the medium 8. Since the grating faces of the condensation and rarefaction waves are concentrical and always satisfy Bragg conditions with respect to any of the concentrical circles intersecting with the incident light of arbitrary angles, the device may be easily used without requiring strictness in the angle adjustment of incident light in use.
