Author Affiliations +
The paper covers an autocollimating fiber optic sensor for measuring the birefringence of bulk material based on the use of a pulsed laser and multimode optical fiber with a fiber delay line. The specimen birefringence is defined by measurement of the pulse intensities. The basic expressions that describe the operation of the sensor are presented. The suggested scheme can be used for studying ht inner stress in transparent solid bodies, birefringence of crystals, or for measuring temperature, pressure, electrical and magnetic field strength, etc.
