Abstract: An apparatus for reading images of a photographic film disposed on an image reading optical path, with a light source (31a) for emitting visible light and infrared light into the image reading optical path to irradiate the photographic film, and a zoom lens unit (32a) for the visible light and infrared light irradiating the photographic film. A visible light sensor and an infrared light sensor are disposed separately for detecting a visible image based on the visible light from the zoom lens unit, and for detecting an infrared image based on the infrared light from the zoom lens unit, respectively. A focal position varying transparent element (FT) is provided for shifting a focal position of the zoom lens unit along an optical axis. The transparent element is movable to and from a position between the zoom lens unit and infrared light sensor to correct variations in the focal position occurring with variations in magnification of the zoom lens unit.

Abstract: A motion sensing system is disclosed having a housing or mounting, a sensor, a shield and a cover. A spacer and a printed circuit board may also be included. The cylindrical shaped sensor is placed within the cup shaped shield with the spacer disposed between the sensor and the printed circuit board. The shield and the printed circuit board are then fastened together. Next, the bottom or nose of the mounting shield is placed into the dish shaped cover and the combination is fastened to the housing with the cover extending into an opening in the bottom wall of the housing. The system allows a downward looking motion sensing capability in addition to the typical forward sensing capability which may also be installed in the housing. The housing may then be connected to a security lighting fixture. An even simpler version is a motion sensing system having a simple mounting for a two transducer PIR sensor where one of the transducers is covered and a Fresnel lens is absent. An effective short range motion detector results and the sensor may be aimed in any direction.

Abstract: In a multistage active infrared sensor, the light emitters 11A, 11B, 11C emit infrared signals which contain distinct channel information. These light emitters 11A, 11B, 11C emit the infrared signals at different timings from each other. This sensor judges whether the infrared signals received by light receivers 12A, 12B, 12C contain channel information of opposite light emitters 11A, 11B, 11C. The sensor cancels any infrared signal which does not contain the channel information of the opposite light emitters 11A, 11B, 11C.

Abstract: A microwave-enhanced infrared thermography technique for detecting buried objects exploits varying phase shifts experienced by different-frequency microwave signals reflected from objects back toward the surface, the phase shifts resulting in different interference patterns and therefore different temperature distribution patterns near the surface. Respective infrared images of an area are captured prior to microwave heating, after a first heating with a first frequency, and after heating with a second frequency different from the first. Pairs of the images are subtracted to form temperature rise images showing patterns of temperature rise in the two cycles, and the temperature rise images are subtracted to form a difference image which is analyzed to identify characteristics indicating the presence of buried objects.

Abstract: Tomographic approaches to hyperspectral imaging, such as CTHIS13 (Chromotomographic Hyperspectral Imaging Sensor), can eliminate the need for the slit, filter, or resonant cavity and substantially increase the optical throughput of the system. These systems capture most of the photon energy from the entire spectral band over the entire measurement interval. Uncooled LWIR imaging technology uses thermal based detecting elements that are less sensitive than the competing photon based cooled detecting elements, and require high optical throughput. An uncooled LWIR hyperspectral imager is described that combines a new high optical efficiency spectral imaging technique combined with a high performance uncooled thermal imager. The merging of these technologies in the current invention will significantly reduce the size, weight, and power requirements of LWIR hyperspectral systems.
