A direct view optical sighting system. In certain examples the system includes an eyepiece, an objective that directs scene light to the eyepiece, a laser rangefinder, and a laser rangefinder coupling prism that directs a laser transmit beam from the laser rangefinder to the objective and a laser return beam from the objective to the laser rangefinder. Examples of the system further include a display assembly including a reticle prism and a display coupling prism, the reticle prism being positioned along the optical path between the laser rangefinder coupling prism and the display coupling prism and having a hard reticle formed on a surface thereof. The objective can be configured to produce a first focal plane of the optical sighting system coincident with the first surface of the reticle prism. The display coupling prism is configured to direct display light toward the eyepiece. Examples of the system also include a zoom relay positioned between the display coupling prism and the eyepiece and configured to adjust a magnification of the optical sighting system.

The technology relates to a long-range optical device for a firearm with an objective and an eyepiece, through which an observation beam path is formed for aiming at a target, the long-range optical device further comprising an opto-electronic display device, wherein the display device comprises an LCoS display for displaying variable data or a target mark, wherein a display beam path of the display device runs at least partly in the observation beam path for displaying the remote object.

An optical device includes a toolless rezero system and/or a zero locking system. The rezero system can operate in a first mode in which a scale ring is non-rotatable relative to an axis. The ring can be manually moved to a second mode, where the ring is rotatable relative to the axis, so alphanumeric characters and bars can be moved about the axis to align a preselected zero element with a reference element and rezero the device. The zero locking system can include a locking cover button that is manually movable to automatically operate a locking ring in a first mode in which it rotatably couples the dial with an adjusting pin to move a reticle, and in a second mode in which it couples the adjustment dial to an immovable wheelbase so the dial is non-rotatable, and the reticle is locked in position. Related methods are provided.

A method for supporting medical interventions using an augmented reality system is disclosed, which comprises determining, using a position marker and an electronic tracking system, positions of a set of points; calculating a geometric shape using the determined positions of the set of points; and displaying, on an optical head mounted display the calculated geometric shape in the field of view of a bearer of the display.

Furthermore, a system and a position marker adapted to be used for this method are disclosed.

The application is directed to a locking adjustment assembly for an optical aiming device. The locking adjustment assembly is usable across different optical platforms regardless of the focal length of a particular optical platform. The locking adjustment assembly is operationally configured to be reset to a zero position. The locking adjustment assembly may also provide an automatic lock at a zero position.

A method for dynamic focusing is presented that can be performed by a dynamic focusing controller that can receive images from the image capture device, and for each image, determine a border of the particle within the image, and calculate a pixel intensity ratio of the image based on the border of the particle. The dynamic focusing controller can also calculate a median pixel intensity ratio from the pixel intensity ratios for each image, determine a focal distance direction based on the median pixel intensity ratio, calculate a focal distance based on the median pixel intensity ratio when the focal distance direction is positive, and calculate the focal distance based on a median border width when the focal distance direction is negative. The autofocusing controller can then send an instruction to the focusing mechanism to adjust the image capture device by the focal distance in the focal distance direction.
