摘要：

We describe a prototype near-infrared Michelson stellar interferometer used to estimate stellar diameters by measuring visibility amplitudes. In particular, details are given for the performance of the device, including the stability, limiting sensitivity, and sources of errors in the visibility amplitudes. We compare the results for stars measured in common with the French interferometer at CERGA. An improved diameter for the red supergiant Alpha Herculis is also presented.
