Claim One:
1. A gated time of flight (GT-TOF) camera operable to determine distances to features in a scene, the GT-TOF camera comprising: a light source configured to transmit at least one light pulse train to illuminate the scene; a photosensor comprising at least one of pixel configured to register amounts of light reflected from transmitted light pulses in the at least one light pulse train by a feature in the scene that is imaged on the at least one pixel; and a controller configured to: gate ON and gate OFF the photosensor responsive to times at which the light source transmits light pulses in the at least one pulse train to enable the pixels to register light reflected by features in the scene during each of N different gates; determine a phase angle of a phasor in a two dimensional space based on amounts of light registered by the at least one pixel during each of the N gates; and determine a distance to the feature based on the phase angle.
