Claim One:
1. An imaging system comprising: a primary detector array having a plurality of detector elements sensitive to an input image so as to produce an image signal; an oscillator coupled to the primary detector for inducing a spatial oscillation in the input image relative to the primary detector array, whereby the image signal possesses a spatio-temporal motion signature of the induced oscillation; a secondary array of opponent center/surround detectors, each center/surround detector fed by one or more detectors from the primary detector array so as to extract improved contrast and motion information; an image processor including a calibrator coupled to each detector in the primary detector array with respect to neighboring one or more detectors in the primary and secondary detector arrays for using the image signal during the oscillation for calibrating said each detector; and wherein the oscillator is configured to provide one or more motionless periods in which no oscillation is induced, the system including a timer for direct timing of detector crossings during the motionless period for extracting one of real-time object velocity information and position information of elements crossing secondary array detector boundaries.
