Abstract
A method for determining a distance to an object using an amplitude modulated continuous wave range imaging device includes emitting a modulated illumination signal. The modulated illumination signal is modulated with a pseudo random code. An image sensor is modulated based on the pseudo random code to capture a plurality of samples of the modulated illumination signal reflected from the object. A phase shift between the plurality of samples and the modulated illumination signal is determined.
