Abstract
The operation of a differential absorption displacement transducer based on the optical wedge principle has been successfully demonstrated. The displacement sensitivity of the transducer can be selected anywhere in the range of 0 to 10.35 dB mm-1 by the proper choice of the wavelength. The minimum value of the displacement resolution is +or-2.9 mu m and occurs for an active wavelength of 585.5 nm.Keywords
