COMPACT SCAN HEAD WITH MULTIPLE SCANNING MODALITIES

摘要

A compact, movable scan head (10) has multiple scanning modalities, capable of high speed and high resolution scanning of a variety of samples (20). Stimulation and detection of storage phosphor screens and fluorescent samples (20) are preferably achieved with first and second channels (81, 82) in an optical path of a first side (11) of the scan head (10). The first side (11) preferably has a laser diode light source (14). Reading of reflective and transmissive signals is also possible. A third channel (83) is available in the optical path of a second side (12) of the scan head (10). The third channel preferably provides LED (32) point scanning and reading of fluorescent, reflective and transmissive signals received from the sample (20). The various modalities of the scan head (10) have coincident optical paths.
