Claim One:
1. A mobile or portable device comprising an illuminating arrangement comprising a light source, and at least two amplitude splitting interferometers configured to form at least two interferograms of light emitted by the light source, at least one of the amplitude splitting interferometers comprising two flat reflectors tilted with respect to each other, the illuminating arrangement being configured to illuminate a target region at a distance of from the device by the at least two interferograms, thereby configured to project a structured light pattern onto the target region; an image sensor configured to capture at least one digital image frame of the target region illuminated by the at least two interferograms; and a processing unit configured to obtain image data of the at least one digital image frame, and configured to determine a depth of at least one object location in the target region relative to a reference location on the basis of the obtained image data.
