ABSTRACT:
A compact, movable scan head having multiple scanning modalities and capable of high speed, high resolution scanning of a variety of samples is disclosed. Stimulation and detection of storage phosphor screens and fluorescent samples are preferably achieved with a first and second channel in the optical path of the first side of the scan head. This first side preferably has a laser diode light source. Reading of reflective and transmissive signals is also possible. A third channel is available in the optical path of the second side of the scan head. This third channel preferably provides LED point scanning and reading of fluorescence, reflective, and transmissive signals received from the sample. The various modalities of the scan head of the present invention may or may not have coincident optical paths. Any two of the above channels, or additional channels similar to the above channels, may be incorporated into the scan head.
