A variable magnification optical system with boresight error correction includes a focusing lens to receive light along an optical axis of the variable magnification optical system, with the focusing lens configured to create an image of a target at a focal plane. The system includes a magnification changer disposed along the optical axis, with the magnification changer including an optomechanical drive system to adjust an optical magnification setting of one or more zoom lenses. The system also includes a light source configured to emit a pilot beam into the magnification changer. The system includes a position sensitive photodetector configured to receive the pilot beam exiting the magnification changer. The system further includes a microdisplay optically conjugate to the focal plane, with the microdisplay configured to impose an image of an electronic reticle on the focal plane based on the position of the pilot beam relative to the position sensitive photodetector.

System and method for electronic correction of boresight errors in variable magnification optical systems

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.

A zoom relay system includes an optical element for receiving light from an object. The zoom relay system is adapted to generate an image of the object on an image plane. The system includes a single varifocal lens group positioned along an optical axis. The varifocal lens group includes at least one lens for providing magnification and a varifocal freeform lens including two lens plates. The lens plates are configured to be disposed along a dimension transverse to the optical axis, such that, when the varifocal lens group is moved along the optical axis to adjust the magnification, the lens plates of the varifocal freeform lens are displaced in the transverse dimension relative to each other to provide compensation, such that, when the magnification is changed, a distance between the object and the image plane remains constant.

An optical system with adjustable eye relief includes a relay lens assembly. The relay lens assembly is defined by a collimating lens and a focusing lens. The optical system includes an aperture stop. The aperture stop is configured to shift axially along an optical axis between the collimating lens and the focusing lens. The optical system also includes an afocal lens assembly. The afocal lens assembly is defined by the focusing lens and an eyepiece. Additionally, an axial shift of the aperture stop along the optical axis between the collimating lens and the focusing lens changes an eye relief of the eyepiece based on a transverse magnification of the afocal lens assembly.

A digital booster for an optical system includes an image acquisition unit. The image acquisition unit is configured to acquire an image frame from a non-magnified optic. The image frame includes an aiming reticle imposed by the non-magnified optic. The digital booster includes a display and a processor. The processor is configured to locate the aiming reticle on the image frame, select a sub-frame of the image frame with an aspect ratio that is centered on the aiming reticle of the image frame, perform image inversion and rescaling of the sub-frame, and transmit the sub-frame to the display.
