摘要：

A compact and stable integrated-optic Michelson-interferometer for 0-633/μm wavelength operation with ion exchanged waveguides in glass is demonstrated for optical displacement measurement. The integration of thermo-optic modulators allows the combined detection of fast movement with orthogonal signals, and high-resolution (1 nm) displacement detection with optical heterodyning. © 1990, The Institution of Electrical Engineers.
