Title:

TIME DEPENDENT FLUORESCENCE MEASUREMENTS

Document Type and Number:

WIPO Patent Application WO2005019811

Kind Code:

A3

Abstract:

Methods and apparatus, including computer program products, implementing and using techniques for collecting optical data pertaining to one or more characteristics of a sample. The apparatus has a light source, one or more illumination optical elements, a scanner, one or more collection optical elements, and a device forming an aperture that limits detection of light from the sample. The illumination optical elements direct a light beam from the light source onto the sample. The scanner scans the light beam across the sample. The collection optical elements collect light from the sample and transmit the collected light to a detector. None of the collection optical elements are included among the illumination optical elements. The device forming an aperture limits detection of light from the sample to light associated with a limited vertical depth within the sample, and is one of the collection optical elements.
