Abstract
An apparatus with a common aperture and multiple image recording surfaces with individual filters and/or controlled shutters enables the implementation of several methods of 3-D measurement systems. The parallel nature of the device lends to short measurement times suitable for measuring moving objects. A similar apparatus may be constructed to project multiple images simultaneously or in rapid succession. Elimination of mechanical motion within the projectors and cameras of the prior art reduce the measurement time significantly. A new method of 3-D measurement employing a sweeping light plane and time encoded image recording uses the apparatus. An alternate method maintains a stationary projected light plane through which an object moves as it is measured in 3-D. Another method uses simultaneous projection of light patterns at different frequencies. Another method employs the time of flight of a light pulse and time encoded recording of the reflected energy.
