Abstract: In this paper, a new type small-angle sensor based on the total internal reflection (TIR) and surface plasmon resonance (SPR) theories in heterodyne interferomery is proposed. With the small-displacement sensor, a small rotation angle can be obtained only by measuring the variation in phase difference between s- and p-polarization states. The best theoretical sensitivity of the small-angle sensor is 2x10-4 degree/degree. And its resolution can reach 1x10-7 radian. The sensor has some merits, e.g., a simple optical setup, high resolution, high sensitivity, rapid measurement.


Keywords: Total internal reflection (TIR), Surface plasmon resonance (SPR), Kretchmann’s configuration, Heterodyne interferometry (HI), Small-angle measurement
