Abstract

PURPOSE:To manufacture a three-dimensional diffraction grating by applying an ultrasonic wave in at least one direction of a body, and thus generating a standing wave. CONSTITUTION:Piezoelectric transducers 8 and 9 are pressed by buffer bodies 4 and 5 and rigid bodies 6 and 7 against surfaces of an amorphous body 1, such as glass of a feldspar system and epoxy resin, in an optional shape and after a heat treatment up to temperature that the layers have in the body 1 when an ultrasonic wave is applied at need is carried out, a standing wave is generated by applying an ultrasonic wave of about IG Hz high frequency for several - tens seconds to grow mutual layers of crystal coincident with the period of the standing wave, thus forming a regular diffraction grating. The pitch of the diffraction grating is determined by the frequency of a voltage applied to the piezoelectric transducers, thereby easily manufacturing a diffraction grating which has about 1mum pitch.
