AbstractThe ice tank facility at the Institute for Marine Dynamics has an optional automatic chase control system. This system allows the carriage to closely 'chase' a self propelled model in the tank. The system's controller presently uses a wire (yoyo pot) to sense the model's position. This accuracy of this position sensing method can be impaired by model pitch and heave. To overcome this problem, an optical position sensor has been developed. This device uses a microprocessor controlled CCD (charge coupled device). Preliminary tests on this design indicate that it may be suitable for chase control and other displacement sensing applications were remote position measurement is necessary. [Author's Abstract]
