Embodiment Construction

[0016] Such as figure 1 As shown, a portable rectangular prism installation parameter calibration instrument, the light emitted by the light source 5 passes through the beam splitter a14, is transmitted to the beam splitter b13, and then to the beam splitter c8, and is divided into two paths on the beam splitter c8 Light, one way passes through the beam splitter c8 to irradiate the target object, and the other way goes vertically upwards to irradiate the target object through the reflector 7, and between the light source 5 and the beam splitter a14, the condenser lens 4 and the self-collimating reticle 3 are installed. A laser pointer 10 is installed directly under the beam splitter c8, and the laser beam emitted by it can be used as an indicator light for the upward reflection of the beam splitter c8, and the adjustment seat 9 adjusts the light of the laser pointer 10 to be the same axis, a camera 2 is installed above the beam splitter a14 for angle measurement. An objective...

Abstract

The invention relates to a portable right-angle prism installation parameter calibrator. Light emitted by a light source passes through a beam splitter a, and is transmitted onto a beam splitter b, then transmitted to a beam splitter c and divided into two routes of light by the beam splitter c, one route passes through the beam splitter c to irradiate a target object, the other route vertically goes up, and irradiates the target object via a reflector, moreover, a condenser and an autocollimating reticle are installed between the light source and the beam splitter a, a laser pointer is installed under the beam splitter c, the laser beam emitted by the laser pointer can serve as pointing light for the upward reflection of light by the beam splitter c, and the coaxiality between the light of the laser pointer and the emergent light of the beam splitter c is adjusted by an adjusting base.

Description

technical field [0001] The invention belongs to the field of calibration instruments, in particular to a portable right-angle prism installation parameter calibration instrument. Background technique [0002] The unique optical characteristics of rectangular prisms make them widely used in the azimuth transmission process of navigation and orientation products. A right-angle prism is often fixedly connected to the outer casing of the inertial combination system. After the relative attitude relationship between the right-angle prism and the inertial combination system is calibrated, the navigation orientation of the inertial combination system can be transmitted through the external photoelectric self-collimation method, or Assign the external reference orientation to the inertial navigation system. [0003] The existing calibration instrument uses a granite plate as the carrier, and two autocollimators constitute the measurement unit. The mounting seat of the component unde...
