Abstract:
Non-uniformity in rotational speed of the scanner motor will result in non-uniformity in the placement of laser scan pixels in laser image recording system.A method of gaining liner placement of scan pixels which can achieve line-to-line pixel registration is described in this paper.

Abstract:
Absorptance is a very important parameter in characterizing the relationship between the light energy transfer efficiency and the jet cross,seetion.In this paper we introduced a real time measuring methed and discussed the correction factor for the value in the Si3N4 synthesizing by laser.All of these are valuable in the real time measurement.
