Title: Optical scanning device
Inventor: NISHIMOTO YOSHIBUMI
IPC: G02F1/11
Filed: 1986-08-18
Abstract: PURPOSE:To scan luminous flux at a high speed by moving luminous flux guided out of a guiding-out means according to the movement of a local elastic wave area which is formed in a medium by an elastic wave generating means. CONSTITUTION:When an elastic wave is generated by the elastic wave generating means 3 powered on by a power source 6, an area of optical anisotropy is formed speedily in the medium 4 and moves in the medium 4. Linear polarized light incident on the medium 4 is phase-modulated partially corresponding to a slit area 21 according to the movement of the area of the optical anisotropy in the medium 4 to become elliptic polarized light. Consequently, luminous flux with intensity corresponding to the ellipticity of the elliptic polarized light is projected from an area on a polarizing plate 5 corresponding to the area of optical anisotropy in the medium 4. Namely, the luminous flux is projected from a different area on the polarizing plate 5 so as to such on the polarizing plate 5, and the luminous flux projected by the polarizing plate 5 is guided onto a surface to be irradiated and scans on the irradiated surface. Thus, the luminous flux can be scanned on the specific surface.
