Abstract. Principles of development of static and full pressure sensor based on the use of an optical method of information conversion, is considered. A significant novelty of the proposed sensor is the use of optical CCD arrays as secondary converters, with which it is possible to convert the spatial distribution of the light flux into an electric signal. Results of theoretical and experimental studies of information processing procedures are presented, mathematical models and algorithms for microcontroller that provides for measuring linear displacements of the membranes center and processing signals from the output of the photodetector line when exposed to a light spot are presented. The proposed pressure sensor, in comparison with its analogues, has significantly smaller mass and size parameters, and energy consumption is reduced by more than an order of magnitude.

Keywords: sensor, static pressure, total pressure, membrane, mathematical model, algorithm, optical ruler, light flux source
