Abstract

The transfer functions of single and dual interferometric cavities were measured with 1300nm high power, tuneable fibre laser with a coherence length of 20mm. The interferrogram of the dual cavity is complex. The positions of the surfaces in the cavities were determined using Fast Fourier transforms. A feature of the dual cavity is an increase in the 'effective' coherence length of the source, illuminating a simple common path interferometer. A 4*1 optical switch was incorporated with the laser allowing near simultaneous data to be recorded from up to 4 probes. A potential application for a dual cavity probe is discussed. Â© 2012 SPIE.
