    摘要: The efficiency of an acousto-optic modulator or deflector is increased by re-using the undiffracted beam, causing the same light beam to travel multiple times through the modulator. In order to maintain the bandwidth of the modulator, the multiple passes are made co-axial. A polarizing beam combiner and a waveplate are used to transmit the incoming beam but reflect the beam on the second pass. The gain in the efficiency of the modulator is particularly large for low efficiency modulators.

    摘要: A high resolution two-directional optical scanner, comprising a source of very high frequency light pulses, a first acousto-optic cell for diffracting the light pulses towards an image plane so as to form on a predetermined area thereof a line of pixels corresponding to the data, and a second acousto-optic cell intermediate the first acousto-optic cell and the image plane for intercepting the light pulses diffracted by the first acousto-optic cell and diffracting them towards the image plane in a second direction perpendicular to the line of pixels at an angle dependent on a scanning signal fed to the second acousto-optic cell. The invention is particularly suited for use with flat bed plotters and reduces the need to transport the plotter bed mechanically in order to achieve scanning normal to the direction of each complete scan line.

    摘要: An optical system for focusing a light beam on to an image plane particularly suited for compensating for manufacturing tolerances associated with laser diodes having variable divergence and astigmatism characteristics. The system comprises a collimation lens for collimating the light beam so as to produce a collimated beam in a first plane and an optical shaper having an axis perpendicular to the first plane for correcting distortions associated with the collimated beam and spatially displaced from the collimation lens so as to form the collimated beam on to the image plane. Preferably, the optical shaper includes a pair of cylindrical lenses separated from each other a predetermined distance so as to minimize astigmatism and divergence of the beam. In use, the optical system is adjusted by displacing the collimating lens from the light source so as to produce a collimated beam of light, adjusting the distance between the cylindrical lenses so as to derive a shaped beam having minimal astigmatism and divergence, and adjusting the distance between the collimating lens and the optical shaper so as to focus the shaped beam on to the image plane.
