ABSTRACT:
In a measuring device utilizing birefringence effect, there are provided a device for producing laser light having two components polarized in directions perpendicular to each other and respectively having first and second frequencies; and a birefringence device which receives the laser light and delivers an optical output having a phase difference between the two components which is varied in accordance with the measured quantity. A specific component of the optical output is extracted by an optical analyzer, and converted into an electric signal which is processed thereafter into an output signal representing the phase difference and hence the measured quantity.
