Design of a multielement infrared thermal detector

Solutions obtained in the course of designing integral multielement thermal detectors, in which an array of detector elements of a thin ferroelectric film is formed, are presented. Based on the tools of the CAD system, the parameters of the signal readout circuit of the pyroelectric detectors are optimized and a set of documents for manufacturing an integrated circuit (IC) of the detector with design rules of 0.18 μm is formed. A distinctive feature of the proposed development is the possibility of the parametric trimming of the conversion coefficients due to the repolarization of each element of the ferroelectric array in the process of calibration.     

Process of Manufacturing Sheet High-Temperature Metal Composites by the Method of Pulse Welding

The problems of optimization of the process of manufacturing quality sheet high-temperature metal composites by the method of pulse welding with the use of various matrices and refractory fibers are considered. The high-temperature mechanical properties of the obtained materials and the results of tests of thin-wall metallocomposites of uncooled nozzles of rocket engines are presented.
