Paper Abstract

This paper puts forward a kind of measuring method, double right-angle prisms imaging technique and video graduation technology have been adopted in inspecting laser beam levelness, and realized the measurement and adjustment of laser level. In this article, optic inspection technology, video graduation technology as well as the measuring error analysis and the efficient way of designing regularizing calibrating inspection are discussed in detail. Compare with the traditional way that testing and measuring in an area of fifteen square meters, this instrument can inspect the laser beam levelness error in a smaller test position (500mm), it can be adjusted and assembled easily. Installing and adjusting can be more easy and convenient in this relative smaller space. The instrument accuracy of this paper excels 3', can fully satisfy the requirement of laser level for the levelness of ± 15'. This instrument has been applied in measuring tools enterprise of our country.
