Abstract
The environment within an area is monitored through use of tomographic reconstruction techniques. Signals for use in the tomographic reconstruction are generated optically by a laser which transmits signals to reflectors positioned about the area and then to detectors around or within the area. Several embodiments illustrate the method whereby the signals are generated by sequential illumination of detectors or by simultaneous illumination of detectors.
