The results of experimental studies of instrumental error in-measuring channel triangulation-term optoelectronic system (IPS). Analiziruyutsya choices and influence the design characteristics of the system, the angles of incidence and reflection of the laser radiation on the measurement result of instrumental errors triangulation sensor at the control surfaces of complex shape.

The analysis of the current state and prospects for the creation of semiconductor microelectromechanical systems pressure sensors in Russia and abroad. Main parameters and characteristics of contemporary pressure sensors defined. Tendencies and directions of improvement of sensors based on these systems are defined.

The expressions connecting the crack resistence power characteristic with the conventional mechanical characteristics at dynamic indentation are presented with control procedure at the stage preceding the destruction of material. The experimental results for isotropic pyrographite graphite confirming the reliability of the method and the possibility of its use at non-destructive testing of graphitized carbon materials are obtained.

The principles of assessment of compensation error of background noise interference on results of radio brightness temperature measurement in the radio heat location systems of meteoparameters control are considered at formation of compensation signal on the exit of additional antenna channel with a special form of the polar pattern. The results of a numerical assessment of measurements error at using the two-channel dual mode antenna - are presented.
