Quantitative measure of quality of technical system is proposed. The mathematical models, establishing dependence of erroneous decisions at the control of technical system, are received.

The metrological characteristics of primary measuring transducer of the average power laser radiation with planar sensitive elements are considered. The possibility of development on they basis of position-sensing laser wattmeter with large aperture are shown.

The infological model of units and processes of visibility parameters measurement under laser location test is developed. The model is suite for the wide range of units with local and nonlocal reflectance under quasicoherent laser radiation probing in homogeneous and casual-non-uniform mediums.

The reported CMOS microsystem with digital output is a key element for accurate magnetic measurements. The integrated system includes a magnetic microsensor - double collector lateral bipolar magnetotransistor and signal conditioning CMOS circuitry. The imbalance in collector currents is compensated for by the change of resistance of the collector load in the control circuit of a «И-ladder». The chip is fabricated in a generic 2 µm CMOS process.

The question of experimental verification of the aggregation of technical means of detecting sources of ionizing radiation, when the need arises analysis of measurement data field parameters of various physical nature.
