Abstract: An infrared emitter, which utilizes a photonic bandgap (PBG) structure to produce electromagnetic emissions with a narrow band of wavelengths, includes a semiconductor material layer, a dielectric material layer overlaying the semiconductor material layer, and a metallic material layer having an inner side overlaying the dielectric material layer. The semiconductor material layer is capable of being coupled to an energy source for introducing energy to the semiconductor material layer. An array of holes are defined in the device in a periodic manner, wherein each hole extends at least partially through the metallic material layer. The three material layers are adapted to transfer energy from the semiconductor material layer to the outer side of the metallic material layer and emit electromagnetic energy in a narrow band of wavelengths from the outer side of the metallic material layer.

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 wavelength division multiplexer/demultiplexer (WDM) for use in an optical network and in an optical performance monitor that minimizes increases in insertion losses over temperature variations. The WDM has a structure for holding at least one optical component. A diffraction grating assembly having a substrate is held in relation to the at least one optical component by the structure. A lens assembly having a focal length is held in relation to the at least one optical component. The coefficient of thermal expansion of the lens assembly and structure are approximately equal. The lens assembly is constructed from a material chosen to minimize its variance in focal length over temperature. The grating assembly has an angular dispersion that changes with temperature and the product of the focal length and angular dispersion remains constant over temperature. The WDM further comprises a prism having a change in index of refraction with temperature that is approximately equal to a negative of a coefficient of thermal expansion of the substrate. The substrate has a coefficient of thermal expansion approximately equal to a negative of a coefficient of thermal expansion of air.

Abstract: A portable light source comprises a lamp (10) contained in a lamp box (42), which is housed in a case (41) to significantly reduce the influences of ambient temperature. In other words, the deuterium lamp (10), likely to be influenced by temperature, is enclosed in a double shield structure including the case (41) as well as the lamp box (42). It is known that ultraviolet irradiation of the air generates ozone. To prevent ultraviolet rays from penetrating the cooling air, an ultraviolet window (69) of the lamp box (42) is provided on an extension light guide (70). As a result, the generation of ozone is controlled in the areas where ultraviolet rays exist in the case (41), effectively preventing the fluctuation of output light due to the generation of ozone.

Abstract: A light-weight, portable spectroradiometer provides a real-time data acquisition capability from 0.3 mu m to 3.0 mu m with selectable integration periods, and operates through a Centronics parallel port of a personal computer to program the spectrometer, store data, and to provide real time graphic output. Equipped with two spectrometers operating from a common optical input, high detector efficiency is obtained by structuring the detector elements for maximum energy gathering capability, matched to slit aperture size and orientation. No filters or mechanically driven mirrors are required, thereby permitting a compact, easily portable instrument. If desired, the detector array is readily adaptable to thermoelectric cooling.
