Abstract

A method and apparatus for three dimensional fluorescent analysis of a target in a liquid sample having fluorescent analyte as a target substance or fluorescent label on the target substance. A rotating carousel carries liquid samples beneath a beam having a beam spot at a horizontal plane of the sample. The carousel advances slowly a linear direction during rotation so that a pattern of overlapping spiral scans provide R-theta two-dimensional samples of the entire plane to identify locations of volumes of interest where fluorescence is measurably higher than background. These locations are probed in the depthwise direction to find locations of fluorescent analyte in three dimensions. Light from the analyte or fluorescent label is detected and processed to characterize the target by color, size or other morphology.
