Abstract: A circuit for processing the outputs of an array of photoconductive detectors, includes amplifiers (101) for amplifying the detector outputs and analogue-to-digital converters (109) for digitizing the amplified outputs. The A to D converters oversample the detector signals. A digital processor (110) then applies a linearity correction to the digitized signals. The circuit is particularly suitable for processing the signals from an array of photoconductive detectors in an FT-IR microscope.

Abstract: An infrared imaging microscope, particularly of the type used to carry out FT-IR measurement, has a detector in the form of a small detector array of individual detector elements. The outputs of the detector elements are fed in parallel to processing means which process the output signals. The use of a small array means that the outputs can be processed without the need for complex multiplexing or perhaps no multiplexing at all thus avoiding the reduction in signal to noise ratio which is associated with large scale multiplexing. The small detector array will generally have between 3 and 100 detector elements. Typically the upper limit will be 64 and a preferred arrangement has 16 detector elements.

Abstract: An infrared imaging microscope, particularly of the type used to carry out FT-IR measurement, including a detector in the form of a relatively small detector array of individual detector elements. The outputs of the detector elements are fed in parallel to an electronic circuit for processing. The relatively small array allows the outputs to be processed without need for multiplexing thereby avoiding reduction in signal-to-noise. The detector array may substantially range from about 3 to about 100 detector elements, and is preferably in a range from about 16 to about 64 detector elements.

Abstract: An array of photoconductive elements comprises an array of radiation detectors; an electrical lead connected to the array of radiation detectors; at least one amplifier receptive of an output signal of the array of radiation detectors; a summation device receptive of an output signal of the at least one amplifier; and a positive feedback loop for reducing crosstalk by directing an output signal of the summation device to the at least one amplifier. A circuit processes the outputs of the array of radiation detectors. The photoconductive elements may be operated in a constant voltage mode or a constant current mode.
