摘要:
Image-intensifying devices (for example, glasses, goggles, etc.) suitable for certain commercial and entertainment applications by virtue of their light weight, small size, and economical production are disclosed. In one embodiment, input light passes through an Amici reflector, which is used to adjust the orientation of the intensified image to register it with the real world. In another embodiment, input light passes through at least two Amici reflectors, which are used to adjust the orientation of the intensified image to register it with the real world. In alternate embodiments, at least one Amici reflector folds the light at a non-perpendicular angle and/or input light is rotated by an angle other than (180°). Other embodiments include a field-flattening lens disposed in front of an image intensifier. The intensified image is then sent through a projective lens assembly to reach the viewer's eye.

A wearable system is shown that presents one or more heads-up displays to the wearer. A data source provides information to an image generator that is sufficient to generate one or more display images, which are still or moving, characters or graphical displays. The output image from the image generator passes through a lens, reflects off a curved mirror, and passes back through the lens the other way. The image then passes through two lenses, between which an intermediate image exists. The image reflects off the “lens,” or visor, of the glasses and proceeds to the pupil of the wearer's eye. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.

摘要:
A device independent, frequency driven layout system and method for field programmable gate arrays ("FPGA") which allow for a circuit designer to specify the desired operating frequencies of clock signals in a given design to the automatic layout system to generate, if possible, a physical FPGA layout which will allow the targeted FPGA device to operate at the specified frequencies. Actual net, path and skew requirements are automatically generated and fed to the place and route tools. The system and method of the present invention evaluates the frequency constraints, determines what delay ranges are acceptable for each electrical connection and targets those ranges throughout the layout.

Image-intensifying glasses 100 are disclosed that are suitable for certain commercial and entertainment applications by virtue of their light weight, small size, and economical production, compared to certain other night vision products. In one disclosed embodiment, input light passes through two Amici prisms 144 and 148 and a field-flattening lens 150 to reach an image intensifier 152. The intensified image it produces is reflected off a first folding mirror 162, passes through a lens 154, reflects off a curved mirror 156, and passes back through the lens 154 the other way. The intensified image then passes through two additional, non-doublet lenses 158 and 160, between which an intermediate image exists. The intensified image then reflects off the “lens,” or visor 130, of the glasses and proceeds to the pupil of eye 131 of the wearer. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.

摘要:
An apparatus for enhanced viewing of objects in two separate simultaneous frequency bands of light that is constructed in accordance with the principles of the present invention includes a primary mirror and a moveable secondary mirror that is disposed above the primary mirror to provide a long focal length. A beam splitter splits the optical path into two paths, one for infrared and another path for visible. Various optical elements and devices are described along each path. The secondary mirror is displaced away from its concentric position over the primary mirror to provide shorter focal lengths in IR and visible. Focal Plane Arrays (FPA's) are disposed where desired along both optical paths for real-time viewing and data acquisition. The preferred FPA in visible is a CCD. The preferred FPA in IR is disposed in a Dewar.
