Also, the effect of mirror coatings on the interference pattern and sensitivity of the device are investigated and simulated by using propagation matrix method. In this device, increasing the phase difference between two counter-propagating beams leads to sensitivity enhancement of the device. The results show that by using multilayer coatings with high reflection power on one of the mirrors, in addition to increasing the accuracy of the device, the phase difference between the two beams and thus the sensitivity of the device can be increased.
