Abstract
A three-dimensional imaging and display system is provided in which user input is optically detected in an imaging volume by measuring the path length of an amplitude modulated scanning beam as a function of the phase shift thereof. Visual image user feedback concerning the detected user input is presented.
Claims40
A three-dimensional imaging and display apparatus, comprising:
- a processor;
- a first circuit coupled to the processor for optically detecting user input in an imaging volume;
- a second circuit coupled to the processor for compensating for parallax in the optically detected user input, wherein the second circuit compensates for parallax as a function of a scan coordinate defined by a mirror system position and at least the measured distance from the minor system to a target object;
- and
- a third circuit coupled to the processor for presenting visual image user feedback concerning the optically detected user input.
