Abstract
PURPOSE: To obtain linear and other desired scanning locus, by inserting a prism or a paraboloidal mirror into the scanning diffracted light obtained by irradiating the coherent light to the rotary disc having the diffraction grating having space frequency inclination.
CONSTITUTION: Disc 1 which has the holographic diffraction grating having many segments due to coherent plane wave reference light and spherical object wave light can be rotated with rotary shaft 18 as the center by motor 17. When the parallel beam (reference light) from the coherent light source is irradiated to disc 1, diffracted beam 21 scans object surface 21 in an arc form. If prism 30 is inserted into diffracted light 21 and center beam 32B gives a minimum declination, locus of the scanning beam becomes a straight line. If diffracted light 21 is reflected by paraboloidal mirror 33 and is focused onto object surface 27, the scanning locus becomes a reverse arc. As a result, linear and other desired scanning locus is obtained.
