Abstract
An example rifle includes a rifle scope including a front optics and back optics for imaging a remote object. A parallax compensating device is coupled to the rifle scope. The parallax compensating device determines a zero-parallax setting distance to compensate parallax errors associated with imaging a remote object. The parallax compensating device removes, using the zero-parallax setting distance, the parallax errors dynamically in real time even if a user's head or eyes are misaligned and temperature at the rifle scope or surrounding environment.
Claims20
A rifle comprising:
- a rifle scope including a front optics and back optics for imaging a remote object;
- and a parallax compensating device coupled to the rifle scope, the parallax compensating device determining a zero-parallax setting distance to compensate parallax errors associated with imaging a remote object, wherein the parallax compensating device removes, using the zero-parallax setting distance, the parallax errors dynamically in real time even if a user's head or eyes are misaligned and temperature at the rifle scope or rifle changes.
A method for dynamic parallax compensation, the method comprising:
- providing a front optics and a back optics of an optical system for imaging a remote object;
- coupling a parallax compensating device to the front optics;
- determining, using the parallax compensating device, a zero-parallax setting distance to compensate parallax errors associated with imaging a remote object;
- and
- removing, using the zero-parallax setting distance, the parallax errors dynamically in real time even if a user is misaligned and temperature at the front optics or the optical system changes.
A system for dynamic parallax compensation comprising:
- a tunable optics module (TOM) for focusing at least one image of a remote target to a reticule plane of a front optics of an optical device, wherein the TOM comprises a plurality of refractive plates for tuning a refractive power of the TOM and is coupled to at least one actuator;
- and
- a processing device for receiving data regarding the remote object and determining a zero-parallax setting distance from the received data to compensate for parallax error in imaging the remote object, where the processing device is configured to send signals to the at least one actuator to adjust the refractive plates for tuning the refractive power of the TOM to reflect the zero-parallax setting distance to compensate for the parallax error.
