The structured light imaging device includes a projector including a diffractive optical element, an image sensor, and a processing circuit. The processing circuit is configured to control the projector to emit a beam having a special pattern, and alter an amplitude of the beam during a sensing period. The image sensor is configured to capture an image corresponding to the beam during the sensing period, and transmits the image to the processing circuit. The processing circuit calculates a depth according to the image and a predetermined image having the special pattern. Therefore, the interference phenomenon is reduced.
