Abstract
A position tracking system comprises a transmitter at a first location for producing a signal and an array of plural ultrasonic transducers at a second location arranged in a grid pattern at a plurality of respective discrete locations. The plural ultrasonic transducers are responsive to the signal to produce plural reactive signals corresponding to the signal as received at respective ones of the plural ultrasonic transducers. A computer is responsive to the reactive signals from the plural ultrasonic transducers for continuously determining the position of the array. The ultrasonic transducers are physically separated. The ultrasonic transducers and spatial light modulators share a common backplane.
