The invention relates to area of measuring engineering, in particular to devices for measurement of angular rate by Saniak effect and can be used for measurement of velocity of rotation and angle f turn of movable objects: ships, aircrafts, rockets, etc. Digital measuring device for angular velocity includes micro-controller, random access memory and permanent memory that through common bus are connected to port C of micro-controller, port E of that one is connected to digital measuring device, and optically connected to each other source of optical radiation, first beam splitter, polarizer, second beam splitter, focusing lens, ninety-degree phase changer, fiber-optical Saniac circuit and second focusing lens, output of that one is optically connected through second beam splitter, polarizer and first beam splitter to input of photo-receiver output of which is connected to input of analog-digital transformer through amplifier. The device includes as well communication interface with indicator of horizontal position of movable object, code-controlled power supply source and additional phase changer input of which is connected to output of fiber-optical Saniac circuit, and output is connected to input of the second focusing lens, at that the control input of additional phase changer is connected to output of code-controlled source of power supply source, control input of that one is connected to port B of micro-controller port A of which is connected to output of communication interface with indicator of horizontal position, and port D – to outputs of analog-digital transformer. The invention provides high accuracy of measurement, excludes additive and multiplicative components of systematic error, excludes errors that come to existence because of effect of external destabilizing factors, in particular temperature, pressure, mechanical and acoustic vibrations. |
