Abstract

The invention discloses a method of the spot joint seal in the optical fiber close-spaced linear array. The process is: 1) one end of the standard single mode optical fiber is draw to the micro optical fiber with diameter of 5-25 mum which includes the standard optical fiber and the transition region; 2) Many micro optical fiber which the end is interval and parallel are lain on the silicon base plate coated the magnesium fluoride on the surface with the V groove or the magnesium fluoride base plate with the rectangle groove; 3) the glass sheet coated the magnesium fluoride on the surface or the magnesium fluoride board is set on the micro optical fiber to form the micro optical fiber close-spaced array fixed with the base plate by the ultraviolet glue; 4) the end of the standard optical fiber is connected with the semiconductor laser by the FC interface and the close-spaced micro optical fiber array outputs the spot array. So the invention can improve the imaging precision of the laser phototypesetting system and the focal depth but decrease the demand of the position precision when the film exposures.

Description

Technical field

[0001] The invention relates to a technology for providing optical fiber close-packed line arrays in a laser phototypesetting system, and more particularly relates to a method for realizing light spots in close-packed optical fiber arrays. Background technique

[0002] In laser scanning equipment such as laser imagesetters, laser light plotters and direct plate making machines, one of the main solutions to achieve multi-path optical scanning is to use multiple semiconductor lasers and multiple optical fibers to form a line array of light points as The object plane is then imaged on the image plane (film surface) according to a certain proportion through the imaging system, so as to realize multi-channel scanning.

[0003] However, due to the structure of ordinary fibers, the light in the fiber is only distributed in a small area in the center. For example, a typical multimode fiber has an outer diameter of 125 microns and a core diameter (light guide part) of 62.5...
