Patent ID: 7081817

Claim:
Motion detection apparatus comprising: a detector unit for detecting motion of an object and producing a plurality of detection output signals, including: at least one first detector including at least one sensing element, operative to detect receipt of at least first radiation in the millimeter wave range having a wavelength between 0.05 mm and 10 mm; and at least first radiation input optics comprising an array of multiple optical segments for focusing millimeter wave radiation from first multiple spaced fields of view onto said at least one first detector, said at least one first detector generating a plurality of first output signals in response to receipt of said at least first radiation resulting from motion of said object between said first multiple spaced fields of view; and a processor receiving said plurality of detection output signals from said detector unit, said plurality of detection output signals including said plurality of first output signals, said processor being operative to process said plurality of detection output signals according to predefined criteria and to provide a motion detection output based on said criteria.
