Status of LISA phase measurement work in the US

Currently there are two implementations for LISA phase measurement being investigated in the United States. In this paper, we present the current status of one of these implementations, the socalled zero-crossing approach or stopwatch method. This method uses a technique of counting and timing to make phase measurements. Herein we present a description of the status of an experiment which produces an optical LISA-like fringe which we use to test our phase meter.
