摘要： An observation plug 102 includes a spark plug body 50, an objective optical system 10, and a set of light conduction paths 16. The spark plug body 50 ignites gas in a combustion chamber by an electric discharge in a discharge gap 60, and has an observation hole 4 penetrating in an axial direction at a location dislocated from the discharge gap 60. The objective optical system 10, which is provided in the observation hole 4 to be exposed into the combustion chamber, bends a course of light received from an incident surface 10a facing toward the discharge gap included in an observation area, and forms an image of the observation area within the observation hole 4. The set of light conduction paths 16 is provided in the observation hole 4, and divides the image of the observation area into a plurality of portions to be transmitted therethrough.

摘要： A divided-aperture infrared spectral imaging (DAISI) system that is structured to provide identification of target chemical content in a single imaging shot based on spectrally-multiplexed operation. The system is devoid of spectral scanning acquisition of infrared (IR) spectral signatures of target content with an IR detector and does not require content.

摘要： Spectroscopic chemical analysis methods and apparatus are disclosed which employ deep ultraviolet (e.g. in the 200 nm to 300 nm spectral range) electron beam pumped wide bandgap semiconductor lasers, incoherent wide bandgap semiconductor light emitting devices, and hollow cathode metal ion lasers to perform non-contact, non-invasive detection of unknown chemical analytes. These deep ultraviolet sources enable dramatic size, weight and power consumption reductions of chemical analysis instruments. In some embodiments, Raman spectroscopic detection methods and apparatus use ultra-narrow-band angle tuning filters, acousto-optic tuning filters, and temperature tuned filters to enable ultra-miniature analyzers for chemical identification. In some embodiments Raman analysis is conducted along with photoluminescence spectroscopy (i.e. fluorescence and/or phosphorescence spectroscopy) to provide high levels of sensitivity and specificity in the same instrument.

摘要： In a composite sensor, an arrangement region of thermal image sensors and an arrangement region of range image sensors are arranged so as to overlap each other as seen in the mounting direction. This makes it possible to acquire thermal and range images coaxially, thereby suppressing image misalignment between the thermal and range images. In the composite sensor, a seal body formed by mounting the first and second substrates on top of each other seals a space about the thermal image sensors in a vacuum state. This can prevent the heat occurring about the range image sensors from affecting the thermal image sensor side. In addition, the substrate arranged with the thermal image sensors and the substrate arranged with the range image sensors are separate from each other, which can secure a degree of freedom in designing.
