“…The parallel method has been demonstrated with up to 16 simultaneous channels, [1,2] with one paper proposing up to 625 channels, although no hardware for this extremely high channel count system was shown. [3] The second scheme automates the typical point scanning by using the individual pixels of a highspeed CMOS imaging sensor, as an equivalent to a single photodiode. [4,5] By illuminating the entire surface, different locations of the imaged object can then be quickly scanned electronically.…”

The widefield laser Doppler velocimeter is a new measurement technique that significantly expands the functionality of a traditional scanning system. This new technique allows full-field velocity measurements without scanning, a drawback of traditional measurement techniques. This is particularly important for tests in which the sample is destroyed or the motion of the sample is non-repetitive. The goal of creating "velocity movies" was accomplished during the research, and this report describes the current functionality and operation of the system. The mathematical underpinnings and system setup are thoroughly described. Two prototype experiments are then presented to show the practical use of the current system.
