Laser beam image recording apparatus |
摘要 |
A laser beam emitted by a semiconductor laser is applied through a beam shaper optical system to a recording film to produce the image of a near field pattern of the laser beam which is of a narrow width in a main scanning direction of the recording film and which has a wide, substantially rectangular intensity distribution in an auxiliary scanning direction. The image recorded on the recording film is free of image density irregularities in the auxiliary scanning direction.
