Abstract: An infrared camera including optics and a detector sensitive to infrared radiation is used in conjunction with at least one light source, such as a laser, to locate a reference point on a target. Two intersecting line segments are produced by the one light source or a combination of two light sources to locate the reference point on the target. The infrared camera would display both an infrared image as well as a visible image which can be merged onto a single display. The teaching of the present invention could also be used to determine the distance to the target as well as the area of the target.

Abstract: An infrared camera provided with a rotating lens. The exterior of the camera is also provided with a touch screen display as well as a switch device such as a 5-way switch, controlling many of the functions of the infrared camera. The rotation of the lens would allow an operator to view different objects while maintaining a single position, allowing the operator to view the material projected on the display very easily. A trigger would be used to capture a particular infrared image and to save this image as well as to transmit it, at a later time, to a personal computer.

Abstract: The present invention is directed to a method for improving measurement accuracy of infrared imaging radiometers utilizing a small pitch infrared detector array. The detector offset is changed so that the detector output, when observing a particular object temperature, is maintained at a desired level over a range of ambient temperatures.

Abstract: The present invention is directed to a method for improving measurement accuracy of infrared imaging radiometers utilizing a small infrared detector array, for example 160×120 pixels. The detector offset is changed so that the detector output, when observing a particular object, is constant over a range of ambient temperatures resulting in a constant dynamic range. A radiometric deconvolution is used in order to correct for measurement inaccuracies due to an object's small size.

Abstract: The present invention is directed to a system for modulating thermal infrared radiation for a pyroelectric imaging sensor or similar sensor by providing two discs rotating at the same speed, both discs provided adjacent to one another and between a source of radiation and a radiation sensor. Each of the discs is provided with a solid portion and an open portion. Changing the orientation of the solid portions of each the discs with respect to one another would change the sensitivity of the modulation device.

Abstract: An intensifying system adapted to be affixed to an electronic imaging device such as a single lens reflex camera or a video camera. The system includes a central intensifying unit for intensifying an image at lower light levels. A back body adapter and a front lens adapter would combine with the central intensifying unit and would be attached to the body of the camera. An electronic objective lens which is normally attached to the camera, would be removed and would be affixed to the front lens adapter.
