Paper Abstract

There is a problem of creation of the system of the halftone and colored laser-beam recording of high resolution. Obstacles have influence on them more than on binary systems of laser- beam recording. Periodical fluctuations of speed of scanning are particularly dangerous. These fluctuations are connected with the vibration of the mechanism of movement of the light sensitivity material. They create a parasitic effect on the recorded image. The cardinal way of disposing of the problem is recording on an immovable material. These records can be made by the system of the two-coordinate angular scanning of the laser-beam. This system has geometrical distortions. Questions of correction of geometrical distortions are considered in this article. An objective with negative distortions is proposed by us for correction of geometrical distortions of one coordinate. We propose to make a correction of the geometrical distortions for a bi-coordinate scanning system by an electronic method. The essence of the electronic method is a modulation of the timing frequency of recording by a function of the correction of distortions. A module of the two-coordinate scanning was elaborated and investigated. The module contains two deflectors, an interferometric system, a block of the control and a three-lens objective with negative distortions. Resolution of scanning of the module is 10,000 X 10,000. Area of recording is 300 X 300 mm. Horizontal sweep frequency is 150 Hz. Error of the position of a beam is +/- 0.002 mm.
