Diode laser direct modulation heterodyne interferometer.

A new type of heterodyne interferometer was made through direct modulation of a diode laser wavelength. A measurement accuracy of better than lambda/50 and repeatability of lambda/100 were obtained. This interferometer shows promise for use in testing wavefront aberrations, especially in optical disk systems.
