    Abstract: Disclosed is a light sensor circuit which works by producing in a photoelectric converting element a photo current proportional to a quantity of incident light falling thereon, converting the photo current into a voltage signal by using a threshold region characteristic of a transistor with a logarithmic output characteristic in a weak inverse state and producing a sensor output corresponding to the voltage signal. The light sensor circuit is provided with an initializing means for removing an electric charge remaining in a parasite capacitor of the photoelectric converting element before detecting light by the same element, thereby achieving a wide dynamic range and obtaining a sensor signal with no afterglow even if it works with a small quantity of incident light.

    Abstract: Submicron diameter particle detection utilizing a high density array is disclosed. The high density array, such as a charge coupled device, is utilized to detect light scattered at a sensing region by particles illuminated by a light source, such as a laser source. Charge storage is utilized to buffer each data frame transferred from the high density array and the multiple serial outputs are processed by parallel processing that includes threshold detection and analog-to-digital converting. A micro-computer and associated digital storage receives the digital outputs and provides outputs indicative of submicron particle sizing. Further improvement in minimum detectable particle sizing of particles carried by a fluid is realized by use of beam shaping optics to shape the illumination beam passed through the sensing region to form either an astigmatic (highly elliptical) beam cross-section, with the fluid being directed towards the imaging system orthogonal to the object plane, or a circular beam cross-section with the flow directed parallel to object plane, and with the focal point of the beam being substantially centrally positioned within the sensing region in either case.

    Abstract: An apparatus and method for providing a real-time video display and a temperature map display of an object, in particular a flame, comprises a single CCD video camera and optical equipment which focuses separate light bundles onto a photosensitive surface of the camera. A separate band pass filter is used in each light bundle to filter selected different wavelengths of light. The video signal from the camera is used in a video digitizer to obtain data which can be used to calculate a temperature map based on the different wavelengths of light of the two bundles. The video signal is also used to produce a real-time video display of the object.

    Abstract: A color detection and/or recognition apparatus comprises a twin row array (16) of detector elements, each element being arranged to produce an electrical signal on detection of a given color. The two rows (21, 22) each comprise a plurality of groups of detector elements, with the elements in each group of at least one of the arrays being sensitive to a respective different color, with corresponding elements in the two rows being sensitive to different colors, and with the four elements of adjacent corresponding pairs of elements in the two rows being sensitive to at least three different colors. THe electrical signals are processed to provide a determination of the detection of color or the recognition of a color. The two rows of detector elements, typically photosensitive sites in CCD arrays, may be formed closely adjacent one another on the same semiconductor substrate, together with CCD shift registers (23, 24) along the outside edges of the two rows. A line buffer delay circuit (25) may be provided for the outputs of one of the rows.

    Abstract: A 2-D sensor array includes a semiconductor substrate and a plurality of pixels disposed on the semiconductor substrate. Each pixel includes a coupling region and a junction region, and a slab waveguide structure disposed on the semiconductor substrate and extending from the coupling region to the region. The slab waveguide includes a confinement layer disposed between a first cladding layer and a second cladding layer. The first cladding and the second cladding each have a refractive index that is lower than a refractive index of the confinement layer. Each pixel also includes a coupling structure disposed in the coupling region and within the slab waveguide. The coupling structure includes two materials having different indices of refraction arranged as a grating defined by a grating period. The junction region comprises a p-n junction in communication with electrical contacts for biasing and collection of carriers resulting from absorption of incident radiation.

    Abstract: A method is provided for setting up a photon counting detector, to enable it to carry out a centroiding procedure in which a photon event occurring in a given range is allocated to one of a plurality of channels into which the range is divided. The method comprises the steps of: a) sub-dividing the range into a plurality of channels of preferably equal width and loading the channel boundaries into a look-up table; b) performing an integration on a flat field and allocating photon events to the channels defined in step a); c) counting the number of events allocated to each channel; d) altering the channel boundaries in directions tending to equalise the number of events allocated to each; and, optionally, e) repeating steps b), c) and d) until the variation between the numbers of events held by the channels is at an acceptable level.
