Method and apparatus for generating three-dimensional occultation imaging from slim profile lighting assembly

A lighting assembly for generating occultation imaging, comprising:

• a plurality of light emitting diodes (LEDs) disposed on an illuminator substrate and configured to emit light therefrom;
• at least one mask defining an obscuration pattern and configured to obscure some of the light emitted from the plurality of LEDs and to produce unobscured light corresponding to the obscuration pattern;
• and
• a reflection chamber having an input surface that receives the unobscured light, at least one reflective layer defining an interior chamber configured to generate multiple reflections of the unobscured light, and an output surface that allows light from the multiple reflections to outside the reflection chamber,
• wherein the at least one mask is located between the illuminator substrate and the interior chamber.
