Abstract: An optical engine (15) for an SLM-type display system, which may be either a front or rear projection system (10, 20). The optical engine (15) provides for a high contrast, telecentric illumination angle to the SLM (33) without compromising brightness by vignetting due to offset in the pupil. The resulting offset pupil is converted to a telecentric, on-axis image by a relay path (34) between the SLM (33) and the projection lens (37). The relay path (34) places the image at an intermediate image plane accessible by a the projection lens (37), which permits the projection lens (37) to be telecentric without an offset pupil.

Abstract: A vehicle (10) includes an infrared imaging system, which has a collection device (22) that collects infrared radiation and supplies it through a cable (24) to a head-up display (27). The head-up display includes an image generator (41) which produces a visible image corresponding to information collected by the collecting device, a lens (43) through which the visible image passes, and a reflector (46). The reflector is a portion of the vehicle windshield (14), and reflects the visible image toward the eyes of a driver (11). The lens has on one side a Fresnel lens surface (56) with a rotationally symmetric power, and has on the opposite side a Fresnel lens surface (57) with a cylindrical power that compensates for asymmetric factors such as the curvature and tilt of the windshield.

Abstract: An infrared imaging system (10) includes a catheter (11). The catheter is inserted into a small passageway, such as a blood vein (23), in order to collect infrared information from the vein. The information is refracted by at least one lens (32, 46, 52, 57, 63) in a collecting section (17, 45, 56, 61) of the catheter, and is imaged onto the ends (38) of an array of optical fibers (34). The fibers transmit the information to a relay lens (42), which images the information onto respective detector elements of an infrared detector (12). The infrared detector converts the information received from the relay lens into electrical information, which is transmitted to a circuit (13). The circuit generates electrical data that is transmitted to a display (16), which displays a visible image based on the infrared radiation emitted by the scene.

Abstract: A golf putter includes a head having a face arranged for impacting a golf ball, a hosel having a lower end connected to the head, and a shaft connected to an upper end of the hosel. The hosel includes a leg portion extending upwardly from the head, and at least one vibration absorbing insert is disposed in a hole formed in the hosel leg portion. The vibration absorbing insert is preferably formed of polyurethane. The head may be formed of heavyweight material such as stainless steel, and the hosel may be formed of lightweight material such as titanium.

Abstract: A system that provides a head-up display for an operator of a vehicle includes a collection device that can collect infrared energy and an image source coupled to the collection device. The image source can generate a visual image based on the collected infrared energy. The system also includes a lens through which the visual image passes before presentation to the operator of the vehicle and a reflector that can reflect the visual image before presentation to the operator of the vehicle.

Abstract: An image display apparatus comprises a main display and an auxiliary display. The main display is used to produce a volumetric image such as graphical image, and the auxiliary display is used to generate two dimensional image such as text image. The auxiliary display is located adjacent the the main display and being able to move relative to the main display along a path extending in a direction substantially circumferential to the main display.

Abstract: An offset reverse telephoto projection zoom lens 300 comprising a moving zoom group 302, a moving compensation group 304, and a fixed rear lens group 306. According to one embodiment of the projection lens, the zoom group 302 has four lenses, the compensation group 304 has four lenses, and the fixed rear group 306 has three lenses. An aperture stop 308 is located in the fixed rear group 306. The fixed rear group 306 has a small diameter which helps alleviate interference with illumination optics. Additionally, a fixed rear group 306 does not require zoom mechanisms at the rear of the lens 300 where space is at a premium.

Abstract: There is disclosed a method and system for controlling the optics of a coherent light source impacting a three dimensional defined volume. The system uses a scanner to time and spatially position the coherent light. The divergent light beam output of the scanner is then placed through positive and negative lenses to narrow the beam waist while also increasing the divergence angle of the beam. Provision is made to abate the divergence angle so that the light, as it impacts the defined volume, will not continue to diverge, creating a skewed image within the volume.
