LED POINT SCANNING SYSTEM |
摘要 |
An LED point imaging scanner for stimulating and reading fluorescent and reflective signal radiation from a target sample (10) is disclosed. LED light source (12) is mounted on scan head (20) and focused into pinhole aperture (15) of spatial filter (30), then collimated and focused to a spot (17) on sample (10). The spatial filter, or an optical fiber equivalent, effectively restricts the incoherent LED light and creates a point light source. Signal radiation from sample (10) is collected through scan head (20) and the returning light beam is collimated and focused onto detection means (40). A spatial filter (22) in the path of the returning beam may also be utilized. Detection means (40) is either a small detector directly mounted onto the scan head, or an end of an optical fiber which transmits the point image to a remotely-positioned stationary detector. The scan head is moved along one or two axes relative to the sample.
