Abstract: A raster scanner (10) with laser (15) for generating a scanning beam (25) and compact, folded optical system for transmitting the beam to the object to be scanned. The optical system includes a modulator (27) for modulating the beam in accordance with video image signals and a rotatable polygon (35) for scanning the beam across tne object to be scanned. The laser is supported at one end in a part-spherical bearing (58), permitting pivoting of the laser about a point (P) coincident with the optical axis (0) of the scanner, and at the other end by screw type adjustors (81) which are used to adjustably displace the laser about the pivot point and so align the axis of the laser beam with the optical axis of the scanner. Scanner operating circuits are provided including a circuit enabling one or both of the scan detectors to serve as a light meter when aligning the laser.

Abstract: An optical apparatus (10) includes a laser (15) for generating a scanning beam, and compact, folded optical system for transmitting the beam to an object (11) to be scanned. The optical system includes a modulator (27) for modulating the beam in accordance with video image signals, and a rotatary polygon (35) for scanning the beam across the object. The laser is supported at one end in a spherical bearing (56), permitting pivotal movement of the laser about a point (P) coincident with the optical axis (0) of the apparatus, and at its other end by screws (81) which are used to displace the laser about the pivot point and so align the axis of the laser beam with the optical axis of the apparatus.
