Aspects of the subject matter described herein relate to attributing light
emissions to spots a light was scanned over. In aspects, the scanned
light includes light capable of increasing light emissions from at least
one type of matter. A detector detects emitted light that comes from
spots the light was previously scanned over. Circuitry attributes emitted
light with spots within the area. Data representing light that reflects
from each spot may be combined with data representing light that emits
(if any) from each spot to create an image. The emitted light may be
assigned a false color in the image to distinguish it from reflected
light in the image. Emitted light may occur as a result of fluorescent
activity. Other aspects are described in the specification.
