Abstract: A modular hyperspectral thermal camera that combines a wide field-of-view with a low erroneous recognition rate is described. The modular hyperspectral thermal camera provides such low erroneous recognition rates without any requirement for cryogenically cooling the associated optical components. The modular nature of the hyperspectral thermal camera permits easy exchange of the optical components and so provides a device that is easily calibrated and varied in resolution. In addition the modular nature allows the hyperspectral thermal camera to be readily converted to a broad band thermal camera, a full field spectrograph or a thermal bandpass filter camera, as required.

Abstract: A UV spot curing lamp assembly comprises an integral filter support and shutter stop mechanism. The assembly includes a UV lamp and a light guide spaced therefrom for receiving filtered light from the lamp and for directing light through the light guide to a selected target or work site for curing materials thereat. A filter plate in the form of a borosilicate glass, having a selected thickness for the particular application, is disposed in relatively close proximity to the entrance surface of the light guide. A movable shutter plate, having an opening therethrough, is disposed between the filter and the light guide entrance surface. The shutter is movable from a first position wherein the opening is in registry with the light guide entrance surface to receive light from the lamp to a second position wherein a solid portion of the shutter plate blocks light from being received by the light guide entrance surface. Effective cooling of the lamp assembly is provided by a fan by which forced air is drawn over the lamp and the integral filter support and shutter stop, and by an internal mounting system configured to direct the drawn air for effective convective heat dissipation.

Abstract: An apparatus, system, and method for solid state spark detection are disclosed. A semiconducting photodetector has a pair of electrical conductors for carrying an electrical current generated when the semiconducting photodetector receives light energy generated by sparks. An electrical current detector is operably coupled with the electrical conductors for sensing the electrical current generated to signal receipt of the light energy generated by sparks. The present invention can be coupled to a monitoring device, such as an oscilloscope, for monitoring intensity and/or timing of spark phenomena. A plurality of semiconducting photodetectors and associated electrical current detectors may be used in concert if desired. The semiconducting photodetectors are suitably adapted to respond to light energy of different magnitudes or wavelengths to more particularly study sparks of different natures.
