Internal drum recording apparatus provided with a rotating deflecting element, comprising two (or more) beams of different wavelengths, which are simultaneously operatable, and optical elements for bringing the two or more beams to a common optical path before they reach the rotating deflecting element. The deflecting element may have dispersing properties such that beams of different wavelengths will leave it at slightly different angles. The beams of different wavelengths may be generated by laser diodes or tunable laser diodes. The apparatus may further comprise a beam combiner to combine the beams generated by the light sources.

Multibeam multi-wavelength internal drum recording apparatus

Laser scanning apparatus includes a machine frame, a first supporting member for supporting a working medium, and a second supporting member for supporting at least the delivery end of a laser beam delivery system. One of the supporting members, preferably the latter one, is a movable carriage mounted in cantilever fashion from one side of the machine frame for effecting relative movement between the working medium and the laser beam delivery system to cause the laser beam to scan the working medium.

Laser scanning apparatus

Laser scanning apparatus comprising stationary optical laser source apparatus for producing a scanning beam and a reference beam, beam delivery apparatus for delivering the scanning beam onto a surface to be scanned, beam position detector apparatus for measuring the position of the scanning beam by sensing the position of the reference beam and fiber optic apparatus for delivering the scanning beam and the reference beam from the optical laser source apparatus to the beam delivery apparatus.

Laser scanning apparatus having a scanning beam and a reference beam

A coupling device for coupling a laser beam into an optical fibre includes a base plate carrying a laser holder and an optical fibre holder substantially aligned with each other along a common axis. The optical fibre holder includes an inner housing disposed within an outer housing and formed with a bore for receiving the end of the optical fibre. One housing includes pin adjusting means for adjusting the received end of the optical fibre substantially parallel to the common axis; and the other housing includes pin adjusting means for adjusting the received end of the optical fibre substantially perpendicularly and/or angularly to the common axis.

Coupling device for coupling a laser beam into an optical fibre

A laser beam scanner comprising a laser source, apparatus for producing a scanning beam and a reference beam which are generally parallel, apparatus for directing the scanning beam onto a surface to be scanned, and apparatus for determining the position of the scanning beam in real time in two dimensions by sensing the position of the reference beam, and wherein the apparatus for sensing the position of the reference beam comprises a grating disposed along a scan axis and defining a multiplicity of first grating lines along the scan axis, which permit the definition of the position of the reference beam in a first dimension, a second grating line disposed across the multiplicity of first grating lines and first and second sensors disposed at respective sides of the second grating line, for sensing the relative amount of light impinging above and below the second grating line, for permitting the definition of the reference beam in a second dimension, whereby the position of the reference beam may be determined both along the scan axis and perpendicular thereto at every location along the scan axis.
