Abstract

A light-splicing method for implementing multi-channel output on laser typesetter to increase output speed is disclosed. A laser signal from the laser device is partially reflected to an acoustooptical modulator by a half-reflecting half-transmitting mirror. The transmitted laser signal is reflected to another acoustooptical modulator by reflector. According to control signal, the laser signal is diffracted into multiple channels of laser signal by said acoustooptical modulator. Said two laser signals are spliced by a half-reflecting half-transmitting to become the parallel channels of laser signal. Its system is also disclosed.

Description

technical field

[0001] The invention relates to an electronic typesetting method and system thereof. More specifically, the present invention relates to a method and system for mosaicing multiple outputs on a laser imagesetter. Background technique

[0002] Laser phototypesetting machine is a high-precision output laser imaging equipment. Laser phototypesetting machine uses helium-neon laser (or semiconductor laser) as the light source, and the graphic information and control signals control the work of the acousto-optic modulator through the interface circuit and the driving circuit signal source. , put the 4 (or 8) channels of the modulated first-order diffractive working laser light through the attenuation sheet, and focus them on the photosensitive film on the surface of the vacuum adsorption drum by the optical lens, and form 4 (or 8) channels of parallel light spots after focusing After the high-speed rotation of the optical drum and the horizontal synchronous movemen...
