Title: Optical scanner
Inventor: MAEDA TOMOJI
IPC: G02B5/32
Filed: 1987-11-12
Abstract: PURPOSE:To image a scanning beam to a prescribed pattern by providing a space frequency distribution in which the imaging focal length by a 2nd grating lens changes to various lengths according to the change in the oscillation wavelength of a light source to various lengths to the 1st and 2nd inline type grating lenses, thereby changing the oscillation wavelength. CONSTITUTION:The laser beam (wavelength lambda0) from the laser light source incident on the grating lens optical system is diffracted by the 1st grating lens 11 in the grating lens system and the diffracted light beams of this time are intersected with each other symmetrically with the optical axis. These diffracted light beams are diffracted by the 2nd grating lens 12 and are focused at a focal point Q0. The 1st, 2nd grating lenses 11, 12 have the space frequency distribution in which the imaging focal length by the 2nd grating lens 12 changes according to the change in the oscillation wavelength of the light source and, therefore, the light beams focus without aberrations at the point Q different from the point in the case of the oscillation wavelength lambda0 when the oscillation wavelength changes from lambda0 to lambda. The focus is thus brought to the prescribed pattern by controlling the oscillation wavelength.
