A MODEL NAVIGATOR BASED ON LASER

A method for the determination of the momentary position of a model in a test basin when the model is not on a carriage employs the use of a laser. The laser is the source of two light beams directed at light sensing servo measuring devices. A mathematical computation of the angle of the reflected light beams results in the positioning of the model on a cartesian grid system. The principles of the operation is discussed in detail and a possible application to dredger operations is given. Computation of position problems, accuracy, and range limitations are examined.
