    Abstract: A method of detecting a temperature of an object in a multiple-reflection environment by a radiation pyrometer includes the steps of detecting a radiation strength emitted from a target region of an object, applying a correction to the radiation strength so as to correct the effect of multiple reflections of a radiation emitted from the object, applying a correction to the radiation strength so as to correct a reflection loss caused at an end surface of an optical medium interposed between the object and a sensing head of the pyrometer, applying a correction to the radiation strength with regard to an optical absorption loss caused in the optical medium, and applying a correction to the radiation strength with regard to a stray radiation coming in to the sensing head from a source other than the target region of the object.

    Abstract: Disclosed is a pyroelectric detector with significantly reduced microphonic noise sensitivity that includes a pyroelectric detector element constructed from a z-cut LiNbO3 or LiTaO3 electret. Selective domain reversal is accomplished in the electret by applying an electric field. Electrodes are attached to either surface of the electret spanning the domain reversed region and a portion of the original domain region to create areas of equal and opposite sensitivity. The detector is mounted in an electrically grounded container or housing. The detector may also be constructed having multiple detector regions to accommodate resonant acoustic frequencies of the electret, to function as a position sensor, or both. In other words, the position sensor has multiple domain regions that also accommodate acoustic frequencies. The detector may also be constructed having domain reversed regions placed on the electret in a periodic pattern having a geometry and spacing that is related to the acoustic impulse response of the electret. Needle domains may also be interspersed in portions or throughout the electret to scatter acoustic waves and thereby reduce acoustic noise. Multiple detectors can be produced in a simple and inexpensive manner using shadow masking techniques.

    Abstract: A non-dither spatio-temporal low pass filter method for compensating non-uniformity of the responses of detector elements of an infrared detector array. The methods can be used for one-dimensional scanning arrays and for two-dimensional staring arrays. (FIGS. 3 and 6). First it is determined whether the scene and the detector array have sufficient relative motion for use of a spatio-temporal low pass filter type non-uniformity compensation (NUC) algorithm. If so the NUC algorithm is applied, which recursively uses both spatial and temporal information from near neighbors as a basis to correct fixed pattern noise on the detector array.

    Abstract: An apparatus (20) for performing a temperature measurement function is proposed. It comprises a first circuit (11) and a second circuit (12). The first circuit (11) has a transistor (M1), a resistor (Rtemp), and a parallel arrangement of n diodes (B1-Bn). The second circuit (12) comprises a transistor (M2) and a parallel arrangement of m diodes (C2). An operational amplifier (13) is on the input side being connected to the first circuit (11) and the second circuit (12). This operational amplifier (13) provides a gate voltage for the transistors (M1, M2). There is an output stage with p output transistors (N1-Np), and an output resistor (r*Rtemp). The output stage performs a current to output voltage conversion in order to provide an output voltage (Vtempout) that depends on the actual temperature (T).
