A prism and light transmitter module includes a prism holder, a light transmitter, a prism module, a drive circuit board, a shield, and a fixing assembly. The light transmitter is configured to emit or receive a light beam along a light axis. The prism module includes an inclined plane and is disposed within the prism holder with the inclined plane exposed. The drive circuit board is disposed above the inclined plane, and intersects with the light axis at a first angle. The shield is disposed on the drive circuit board. The fixing assembly connects to the prism holder, is configured to fix the drive circuit board, and includes a hole through which the light transmitter is exposed. A binocular capable of measuring distance includes a first optical system and a second optical system. The first optical system or/and the second optical system include the prism and light transmitter module.

In a visual target acquisition scope system for an adjustable connection is provided between a unity magnification scope producing 1× magnification image viewed by one eye of the user and a photographic lens/viewfinder of a photographic camera viewed by another eye of the user. According to the system, while the user is looking at an object through the unity magnification scope with one eye and looking at the object through the photographic camera lens with the second eye, the target visible with the first eye is also visible with the second eye.

An ergonomic digital imaging system obviates the need for, and replaces, the standard microscope with binoculars for viewing images, thereby freeing the user from using his or her hands to manipulate images seen through the binoculars of the microscope, whereby the user can use his or her hands for other tasks, such as dental or other surgery, from a position away from the exhaled breath of the patient being treated. The images are maintained focused, no matter how close or far the viewer is to the viewing display screen. The system is collapsible and portable, so that specialists can take the system from office to office, a plug and play work environment. The extended maneuverability of the camera head results in simple and fast patient positioning, and the camera and display module adjust for any comfortable sit or stand ergonomics of the practitioner.

A night vision goggle adapter including: a goggle mount assembly; a primary magnet generating a magnetic flux; a magnetic flux conducting unit having a first end and a second end; a first plurality of shunts; and a second plurality of shunts disposed about the goggle mount assembly; wherein the magnetic flux conducting unit may overlap the primary magnet and form a magnetic circuit for conducting the magnetic flux towards the second end of the magnetic flux conducting unit when none of the first plurality of shunts and none of the second plurality of shunts are overlapped by the magnetic flux conducting unit; and wherein the magnetic flux is shorted through one of the first plurality of shunts or the second plurality of shunts when the magnetic flux conducting unit is positioned to overlap one of the first plurality of shunts or one of the second plurality of shunts.

Methods and apparatus enable an image-viewing system to automatically zoom in and out as target subset matter is tracked. A hand-held body with a lens gathers an image including target subject matter. An image sensor having a resolution in pixels receives the image, and a viewfinder displays at least a portion of the image received by the image sensor. By virtue of the invention, apparatus for automatically zooming out the image displayed in the viewfinder if relative movement is detected between the target subject matter and the body and, and automatically zooming in the image displayed in the viewfinder if the relative movement of the target subject matter slows down or becomes stationary. A power zoom lens may effectuate the automatic zooming, or the zooming may be accomplished digitally without moving parts. The body may form part of a camera, video recorder, binoculars or telescope.

The present invention is a lightweight night vision device (NVD) sealed from environmental conditions, shielded from electromagnetic interference (EMI), and having mechanisms for easy adjustment and fixation of collimation and interpupillary distance. The NVD monocular housing is integrated with the eyepiece, image intensifier tube module, and objective, allowing collimation to be fixed via an optical alignment of the monocular housing to its eyepiece, tube module, and objective. Certain components from existing NVDs may be reused in assembling the present invention to provide cost savings.
