Optical automatic attitude measurement for lightweight portable optical systems

摘要

An optical automatic attitude measurement device for a lightweight portable optical system is disclosed. In one embodiment, a first optical device is configured to provide an attitude beam. A second optical device mechanically coupled to the first optical device to a lose tolerance. The second optical device is configured to provide a reference beam and to receive the attitude beam from the first optical device. The second optical device is further configured to obtain an attitude measurement by computing a differential measurement between the reference beam and the attitude beam in x and y planes at room temperature.

1. An optical automatic attitude measurement device for a lightweight portable optical system, comprising:
a first optical device including a sight mirror; and a second optical device mechanically coupled to the first optical device to a lose tolerance, the second optical device comprises:
a light source to generate a beam;a first collimating optic device to collimate the generated beam;a beam splitter cube configured to:
receive the collimated beam from the first collimating optic device and split the collimated beam into a reference beam and an attitude beam;reflect the attitude beam and direct the reflected attitude beam towards the sight mirror residing in the first optical device; andreceive the reflected attitude beam from the sight mirror and pass it through the beam splitter cube, wherein the beam splitter cube is configured such that the reference beam goes through the beam splitter cube and gets reflected back; anda camera configured to receive the reflected attitude beam and the reflected reference beam from the beam splitter cube, wherein the second optical device is configured to obtain an attitude measurement by computing a differential measurement between the reflected reference beam and the reflected attitude beam from the first optical device in x and y planes at room temperature.
