Optical measurement instrument and measurement method using the same

Abstract

The invention relates to an instrument for optical measurement and its measurement method. The measuring instrument includes a laser pointing beam expander, a host, a support and a base. There is a laser pointing beam expander and a longitudinal translation mechanism of the host, and a laser pointing beam expander, a host lifting adjustment mechanism and a horizontal rotation positioning mechanism are arranged between the support and the base; the laser pointing beam expander and the host longitudinal translation mechanism include a micrometer, The laser pointing beam expander and the host horizontal rotation positioning mechanism include a horizontal rotating plate, a rotating rod, a limit block and a horizontal support plate, a support structure and a limit structure, and the laser pointing beam expander and the host lifting adjustment mechanism include a lifting adjustment column I and Ⅱ; The measurement method includes the laser pointing beam expander and the preparatory steps of adjusting the height, longitudinal position and horizontal direction of the host. The invention integrates flexibility, convenience and practicability, thereby reducing labor intensity of workers and improving construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement, in particular to an instrument for optical measurement and a measurement method thereof. Background technique [0002] ​The existing laser pointing device uses a low-power semiconductor laser to emit laser light, which is converged by an optical system to become a highly collimated laser beam, and the pointing work is completed through horizontal and vertical fine-tuning. The existing laser pointing instruments are large in size and have the functions of setting out, positioning, and pointing. Moreover, because the position and pointing of the instrument need to be adjusted frequently during the actual production and construction process, these instruments cannot meet the requirements of high and low positions and longitudinal positions. Or the precise adjustment of the horizontal pointing, etc., so the production and construction process needs repeated adjustments to be in place,...

Problems solved by technology

The existing laser pointing instruments are large in size and have the functions of setting out, positioning, and pointing. Moreover, because the position and pointing of the instrument need to be adjusted frequently during the actual production and construction process, these instruments cannot meet the requirements of high and low positions and longitudinal positions. Or the precise adjustment of horizontal pointing, etc., so the production and construction process needs repeated adjustments to get in place, which is inconvenient to use, labor-intensive for workers, and affects the construction progress.
