  • Scanner/plotter optical system
    Patent number: 4516023
    Abstract: A laser beam scanner with encoder and a laser beam plotter with encoder are disclosed. The scanner provides for unsharp masking by alternating between a large scan beam and a small scan beam on alternate scans. Compensation for non-straight scan lines is achieved through a small linear galvonometer placed in the scanning optics. An equal conjugate optical system is utilized to allow encoder information to be obtained from a stationary image of the main scanning and plotting galvonometer mirror.
