Abstract: The invention discloses a selectable offset image wedge assembly and various methods for making and for use with any optical system having a circular lens and an objective, comprising a housing with a rear-facing end that mounts onto the objective and a forward-facing end with a circular wedge lens mounted therein that is coaxially aligned with the circular lens of the optical system, wherein, the wedge is adjustable to any predetermined clocking position after detachment from the optical system, allowing quick and repeated reattachment to the optical system to an approximately exact vertical orientation of a first image produced by the wedge lens and a second image produced by the circular lens of the optical system.

Abstract: The present invention relates to an offset image wedge for use on a bore-sighted rifle that does not need to be exactly accurately mounted to the rifle because the offset image wedge is mounted directly onto the scope via a clamping mounting device and aligned optically by rotating the clamping mounting device on the scope until dual displayed images overlay each other. The offset image wedge allows for a dual image which allows it to be aligned in the field, and it allows for the user to choose either a bore-sighted image or an offset image without removing the wedge. This dual image capability is accomplished by having a wedge with a smaller diameter than the outer perimeter of the objective lens of the scope of the rifle. The use of a smaller diameter wedge allows the objective lens of the scope to continue to operate normally while the wedge delivers the offset image at the same time.

Abstract: Generating an image includes receiving light associated with spectral bands. The following are repeated for each spectral band: an electrical signal is received at an electro-optical element, an optical property of the electro-optical element is changed in response to the electrical signal to filter for a spectral band, and the spectral band is transmitted to a sensor. The spectral bands are sensed at the sensor. The spectral bands are combined to generate a composite signal, and an image is generated from the composite signal.

Abstract: A machine vision apparatus (24) and method are provided which allows imaging by or with the aid of artificial observation devices, such as video cameras, binoculars, telescopes, and other optical observation devices (10) which have an objective lens (12) passing light from an object or scene being viewed to a focal plane (18) at which is located a surface (22) which is at least partially reflective. Conventionally, such optical observation devices provide a retro-reflective light return into the scene being observed. Such a light return from an observation device can be detrimental, for example, to certain experimental results, or to the accuracy of machine vision (i.e., imaging) employed in robotic manufacturing tools.

Abstract: An iris recognition apparatus (12a) and method includes a camera (22) for imaging the human retina as seen through the pupil. The reflective retina and pupil are imaged as a luminous or retro-reflective spot located in a field of view (26). A direction to the spot (i.e., the retina spot at the pupil within the iris) in the field of view is determined, and a fine-focus video camera (48) is directed along this direction to capture an image of the iris surrounding the pupil of the eye. The captured iris image can be used for unique and individual identification of the human whose eye is imaged using known data storage, retrieval, and comparison methods.
