Apparatus and method for optical assay imaging.

摘要

Apparatus and methods for optically assaying an analyte borne on a support use a light source (24) to irradiate a sample of analyte (26), a light from which is received by a group of memory cells in a dynamic RAM (28) over a given exposure time. The exposure may be repeated over different exposure times. The characteristic of the analyte to be determined is assayed by measurement of the states of the memory cells after such exposure(s).
