By adjusting the first mirror to the correct position so that the interferometer is on the "slope of the fringe", as illustrated above, any change in the cavity length will result in a change of the reflected light due to the slope \$dR/dx\$. In this way, tiny changes of the position of the object can be translated to large changes in the laser power detected by the photodiode. ... ...
