1. An object detection apparatus, comprising:
a casing with an inspection bay;
a coherent light generating assembly configured to generate a coherent light beam;
a coherence breaking optical element, wherein the coherence breaking optical element is a mirror, for changing the coherent light beam into a broken coherence light beam and projecting a broken coherence light beam into an object inspection zone, the object inspection zone defined by a path of the broken coherence light beam and the inspection bay;
a light collecting assembly positioned and configured to receive light resulting from the interaction of an object within the object inspection zone and the broken coherence light beam;
a sensor to receive light from the light collecting assembly and sensitive to the broken coherence light beam for producing image data representative of object contents; and
an electronic board configured to process the image data.
