摘要： Metrology method and apparatus (10) for determining a characteristic of an object's surface. The apparatus includes a multiple wavelength source (12) having an optical output. The source is comprised of a multimode laser diode (18) for simultaneously providing a plurality of wavelengths from which a synthetic wavelength is derived for metrology purposes. The apparatus further includes a beamsplitter (30), preferably a polarizing beam splitter, coupled to the optical output for providing a reference beam (32) and a measurement beam (34), the measurement beam impinging on the surface and the reference beam being phase modulated. The apparatus also includes optical elements and devices for detecting a phase difference between the reference beam and a reflected measurement beam for determining the characteristic of the surface. A diffraction grating (60) is blazed for a nominal characteristic output of the laser diode, such as 785 nanometers, and spatially resolves the various wavelengths of the returned laser light. The resolved wavelengths are provided as two beams by a lens system (62) and are detected by a pair of photodetectors (64, 66). A data processor ( 68) coupled to an output of the photodetectors determines an interferometric phase at the two wavelengths and the surface characteristic.

摘要： The phase ambiguity of conventional interferometers may be removed by using two laser diodes of different optical frequency to generate a synthetic wavelength. However, the stability requirements for a two-color interferometric laser gauge that must provide unambiguous determination of the optical fringe order over a large distance can be severe. The invention determines upper limits on the optical wavelength uncertainity and expresses same as a function of optical path difference between object and reference beams, phase measurement errors and the synthetic wavelength. A wavelength stabilization arrangement involves simultaneous servo control of two laser diodes (10, 12) with a single Fabry-Perot etalon (36). An embodiment of the invention demonstrates its effectiveness for long-term stabilized two-color interferometry over a distance of 250 mm, with a 15 .mu.m synthetic wavelength and a repeatability of 40 nm. For periods of less than 1000 seconds, the repeatability is eight nm.
