Multireflection Microstructure Mapping Prisms

Abstract

The invention relates to a multi-reflection microstructure surveying and mapping prism, comprising: a casing and a prism arranged in the casing, the prism includes a cylinder at one end and a hexagonal pyramid at the other end, the bottom of the cylinder and the bottom of the hexagonal pyramid The coaxial integrated connection is characterized in that each corrugated surface of the hexagonal pyramid is provided with several convex lines protruding from its surface, and each corrugated surface of the hexagonal pyramid is provided with several mutually Parallel 90° angular ridges; or each corrugated surface of the hexagonal pyramid is provided with several 90° angular ridges and several semicircular ridges, the 90° angular ridges and the semicircle The extending directions of the shaped ridges are parallel to each other, and the 90° angular ridges and the semicircular ridges are alternately arranged on the corrugated surface. The hexagonal pyramid plus cylinder structure realizes that the light entering and exiting the prism needs to pass through a cylinder with the same radial size, which functions to filter out the light part from the radial propagation of the cylinder, and the hexagonal pyramid plays a reflective role.

Description

technical field [0001] The invention relates to a precision surveying and mapping optical instrument, in particular to a multi-reflection microstructure surveying and mapping prism. 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 n...

[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
