Title: Scanning optical device with plane tilt correcting function
Inventor: ARIKI YOSHIO
IPC: G02B26/10
Filed: 1989-06-28
Abstract: PURPOSE:To uniformize the spot diameter of a light beam on a plane to be scanned in the scanning direction by interposing an adjusting means, which limits the luminous flux in the direction perpendicular to a scanning direction in accordance with the characteristic of curvature of field remaining on an object to be scanned, between a rotary polygon mirror and a deflecting scanning optical system. CONSTITUTION:Since light beams 34 and 35 have beam envelopes 32, spot diameters on a plane 30 to be scanned are d1 and d2 and they are very varied. The luminous flux of the light beam 34 is so adjusted that the incident beam diameter is smaller than that of the light beam 35, thereby changing the beam envelope 32 of the light beam 34 to a beam envelope 33. Consequently, the spot diameter is d3 and the variance of the spot diameter is reduced. This adjustment is performed is all of the area in the scanning direction, namely, in accordance with the curvature of field 31 while changing the extent of limitation of the luminous flux. Thus, the spot diameter is kept uniform in all of the area in the scanning direction.
