The outputs of amplifiers 26 and 29 are connected to the inputs of the block 40 allocation quadrant angular movements and inputs of the first 30 and second 31 adders. The outputs of the first 30 and second 31 adders are connected to the inputs of the Quad 33 and 34 whose outputs are connected to inputs of the third adder 32, the output of the third adder 32 is connected to the input unit 35 taking the square root, the output of which is serially connected to the filter 36, the stopper 37, block 38 to determine the minimum values of acceleration, calculators 39 minimum amplitude value of the angular displacement and the first input circuit 41 matches, the second input of which is connected to the output selection unit 40 quadrant angular movements, the output of the circuit 41 matches is connected to the input of the Registrar 5.

Emitter 4 light optically connected with sootvetstvujusjie electrical circuits, included in the opto-electronic device, is supplied from the power source 3 ( not shown). The longitudinal axis of the mechanism is perpendicular to the base 2.

Opto-electronic device for determining the angular displacement mechanisms is as follows.

Light emission from the emitter 4 light through the semitransparent mirror 1 passes through a longitudinal slot 8, 42, 43 on the measuring element 17 of the sensor unit 6 and the sensor unit 7. Radiation passing through the cylindrical elements 19 and 20, made of optically transparent material, fall on the photodetectors 14 and 18, causing the background illumination and the appearance of the background current. In the absence of spatial angular movements, leading to the appearance of accelerations, the potentiometers 22 25 is set so that the output signal of the adder 30 and 31 was zero. During angular movements and the resulting acceleration of the measuring element 17 is shifted in the direction of one of the cylindrical elements 19 or 20 and deformed, which leads to an increase of the contact spot. The light beam passes through the contact patch, resulting in an increase of the measured signal to output the cash is supplied to the adder 30. The decrease in the value of the current acceleration causes a corresponding decrease in the strain measuring element 17 and reducing the contact patch.

Thus the value of the signal at the corresponding output of the photodetector is reduced. The appearance of the orthogonal component of the acceleration due to spatial angular movements of the mechanism (which have periodic character) leads to the fact that similar processes occur in the second sensing block 7, which leads to the appearance of the information signal at the outputs of the differential amplifiers 28 and 29, and, as a consequence, the output of the second adder 31.

Information signals with sensitive blocks 6 and 7 correspond to orthogonal components of acceleration arising from the spatial angular movements of the mechanism. The signals of the adders 30 and 31 act on the outputs of the Quad 33 and 34, the output of which they arrive at the input of the third adder 32. With an output of the third adder 32 signals fed to the input of block 35 taking the square root, and therefore the input of the filter 36 is a signal proportional to the main vector of radial acceleration. After the filter limiter 36 and 37 of the amplitude of the signal he Postup the maximum radial acceleration minimum value of the amplitude of the spatial angular movements of the mechanism. A signal corresponding to the minimum value of the amplitude of the spatial angular movements, arrives at the first input circuit 41 matches. To the second input circuit 41 receives the signal from the selection unit 40 preset (program execution sequence of technological operations) quadrant angular movements. When passing mechanism of the minimum amplitude value of the angular displacement and the specified quadrant angular displacement (corresponding to the specified program quadrant) signal with the output of the circuit 41 matches to the input of the Registrar 5 to perform the necessary functions assigned to the node of the mechanism that carries the whole measurement route in General.

Upon receipt of the signal from the electric generator 21 of ultrasonic frequency on the surface of the guide suspension 15 have nodes and antinodes, which reduces friction and allows to measure small values of accelerations, and hence the corresponding angular displacement mechanism.
