Prism Adjustment Base for Optical Surveying and Mapping

Abstract

The invention relates to a prism adjustment seat for optical surveying and mapping, which comprises: a fixed plate, and a guard plate fixed around the circumference of the fixed plate, characterized in that, the fixed plate is provided with three a first fixing hole, and a second fixing hole is arranged on the fixing plate in the triangle formed by the connecting lines of the three fixing holes; when the three first fixing holes on the fixing plate are respectively provided with a prism lens, At this time, the second fixing hole cannot be provided with a prism lens; when one second fixing hole on the fixing plate is provided with a prism lens, at this time, the three first fixing holes cannot be provided with a prism lens. Three first fixing holes and one second fixing hole are set, so that three prism lenses can be used for reflection work at the same time, and it can also be switched to only one prism lens for work, and the reflection conditions of surveying and mapping work are more flexible it is good.

Description

technical field [0001] The invention relates to a precision surveying and mapping optical instrument, in particular to a prism adjusting base for optical surveying and mapping. Background technique [0002] The prism adjustment base generally only has a threaded hole that can be installed with a prism. Under certain surveying and mapping conditions, it is not easy to find the target when the reflection of the prism is disturbed by the surveying and mapping equipment. The repeated adjustment of the reflective prism in surveying and mapping wastes a lot of time and energy, especially in outdoor environments, which need to be simple and fast. [0003] The reflected light intensity of the reflective surface of the prism will be lost, and no good effect will be obtained. In this way, infrared light will be used instead. Although it cannot be observed by naked eyes, it can be observed with the help of instruments. Simple prisms can no longer achieve better functions. It is necess...

[0002] The prism adjustment base generally only has a threaded hole that can be installed with a prism. Under certain surveying and mapping conditions, it is not easy to find the target when the reflection of the prism is disturbed by the surveying and mapping equipment. The repeated adjustment of the reflective prism in the surveying and mapping work wastes a lot of time and energy, especially in the outdoor environment, which needs to be simple and fast

[0003] The intensity of reflected light on the reflective surface of the prism will be lost, and no good effect will be obtained.

In this way, infrared light will be used instead. Although it cannot be observed by naked eyes, it can be observed with the help of instruments. Simple prisms can no longer achieve better functions. It is necessary to modify the surface shape of the prism surface in order to achieve better reflection of infrared rays. Even enhanced infrared
