ABSTRACT:
A detector array for a laser imaging apparatus comprises a plurality of detectors disposed in an arc around an opening in which an object to be scanned is disposed; and a variable gain integrator operably connected to each detector to accommodate the dynamic range of each detector. A method for collecting data for use in image reconstruction of an object being scanned is also disclosed, comprising the steps of providing a plurality of detectors disposed in an arc around the object to be scanned, including a variable gain amplifier connected to each detector; impinging a laser beam at a point on the object; integrating the input to each integrating amplifier at several time intervals; recording each output at each integration interval for use in image reconstruction; orbiting the detectors and the laser beam to a next point on a circle; and repeating steps until a complete circle has been traversed.
