Abstract

We present experimental results for a high resolution interferometer based on dynamic volume holography in photorefractive materials. The proposed interferometer is able to detect small angular deviations (up to 10-8 rad) and wavelength shifts in one of the readout beams of 10 fm. Small changes in the recording beams of the hologram are detected by evaluating the corresponding readout Bragg wavelength.
