Abstract
An example rifle scope includes a plurality of light emitting devices for sending illuminations directed to a distal end of the rifle scope. A plurality of optical detectors detects reflected light received from the distal end of the rifle scope. Each of the optical detectors produces data regarding the reflected light each optical detector observed. A processor device receives the data on the reflected light from the optical detectors and adjusting a position of a field lens so an eyepoint projected in a target space of the rifle scope coincides with an optical axis of the rifle scope removing parallax errors due to misalignment.
Claims20
A rifle scope comprising:
- a plurality of light emitting devices for sending illuminations directed to a distal end of the rifle scope;
- a plurality of optical detectors for detecting reflected light received from the disyal distal end of the rifle scope, each of the optical detectors producing data regarding the reflected light each optical detector observed;
- and
- a processor device for receiving the data on the reflected light from the optical detectors and adjusting a position of a field lens so an eyepoint projected in a target space of the rifle scope coincides with an optical axis of the rifle scope removing parallax errors due to misalignment.
A method for parallax compensation, the method comprising:
- sending, using a plurality of light emitting devices, illuminations directed to a distal end of an optical device;
- detecting, using a plurality of optical detectors, reflected light received from the distal end of the optical device, each of the optical detectors producing data regarding the reflected light each optical detector observed;
- receiving, using a processor device, the data on the reflected light from the optical detectors;
- and
- adjusting, using the processor device, a position of a field lens so an eyepoint projected in a target space of the optical device coincides with an optical axis of the optical device removing parallax errors due to misalignment.
A parallax compensation system comprising:
- a plurality of light emitting devices for sending illuminations directed to a distal end of an optical device;
- a plurality of optical detectors for detecting reflected light received from the distal end of the optical system, each of the optical detectors producing data regarding the reflected light each optical detector observed;
