Abstract:
An apparatus for imaging light from a plurality of laser diodes (504) onto a multi-channel light valve (6) includes a plurality of laser diodes each coupled to at least one fiber waveguide (508). A planar lightwave circuit (408) is coupled to at least one waveguide on a first side (508), and to the multi-planar light valve (6) on a second side.
Abstract:
An apparatus for direct engraving comprises: a plurality of laser diode emitting at different wavelengths; a multiplexer (11) for collecting the plurality of laser sources into a single laser beam; a rare earth doped fiber amplifier (12) to amplify the single laser beam to form an amplified single laser beam; a demultiplexer to split the single laser beam into a plurality of amplified laser sources; and an imaging means to apply the plurality of amplified laser sources for imaging a printing plate (55).
Abstract:
An imaging device includes an image carrier; and an array of ultra-small light-emitting resonant structures constructed and adapted to emit light onto the image carrier, at least one of said ultra-small light-emitting structures emitting light in response to exposure to a beam of charged particles. The image carrier may be a drum. One or more imaging devices may be incorporated in a copying machine; a printer; or facsimile machine.
Abstract:
To provide a multichannel drive circuit capable of driving the load of each channel constituting a load array for all the channels under a uniform condition even if the circuit characteristics of the channels including the current source differ from one another attributed to the semiconductor manufacturing process. A multichannel drive circuit comprises a channel-to-channel common connection line (5) for electrically interconnecting the current paths of the channels connecting the current sources of the channels constituting a current source array (11) to the input switches of the channels constituting an input switch array (13) and current-blocking means (12) for blocking the output currents from the current sources of the channels the input switches of which are off out of the channels from flowing to the channel-to-channel common connection line.
Abstract:
Method and device to generate a dot (67) on a medium (23) by depositing a spot (22) on a medium (23) using a VCSEL light source (10), whereby a light beam (11) is generated using a VCSEL light source (10), the energy distribution of the generated light beam (11) is reshaped using a wave front engineering element (20) into a light beam (21) with a reshaped energy distribution to deposit a spot (22) on the medium (23).
