ABSTRACT:
A scanning apparatus including a cylindrical member and an optical system. The cylindrical member rotates about a rotational axis and has an outer surface to support a storage phosphor sample thereon. The optical system moves in translation parallel to the rotational axis to scan the sample. The optical system comprises an opening, an excitation beam, an integrating member, and a single detector. The excitation beam is directed through the opening to impinge on a sample and cause light to be emitted from the sample. The integrating member reflects the emitted light using an interior three-dimensional polynomial surface providing diffuse reflection. The single detector is disposed adjacent the integrating member for collecting the reflected emitted light.
