OG exemplary drawing
 
1. An apparatus to illuminate and capture images of airborne particulate matter collected on a deposition surface comprised of:
a. multiple controlled light sources situated in a ring surrounding the airborne particulate matter and emitting ultraviolet, visible, and/or near infrared electromagnetic light at a high angle of incidence to the top surface of the airborne particulate matter;
b. an imaging unit oriented to observe the airborne particulate matter and situated adaxial to the light sources;
c. a control unit for the light sources and the imaging unit which individually modulates the light sources and activates the imaging unit so as to capture a series of images of the airborne particulate matter illuminated from different adaxial directions, over a range of the electromagnetic frequencies, and across a range of illumination intensities.
