Elastooptical antenna for detection of gravitational radiation.
Using the photoelastic effect in transparent solids to detect stresses induced by a gravitational wave is proposed. The induced birefringence is measured by a polarimeter. The phase difference is amplified by a Fabry-Perot cavity containing the medium. The sensitivity of this optical strain sensor is discussed, and that of the antenna is estimated.
