Abstract:
A biochemical assay device for optically scanning individual wells in an assay plate, comprising:an imaging system including: a light propagating substrate for overlaying the assay plate; a plurality of pixel locations defined on the substrate, each pixel location aligned with a well in the assay plate; means for selectively outputting from the light propagating substrate an incident beam of light at each pixel location to individually scan each of the wells in the assay plate, wherein an emission beam of light is generated from the scanned well in response to illumination by the incident beam of light; and means for detecting the emission beam of light from each scanned well; a driver circuit operable to control the selective outputting of the incident beams of light and to control the selective receiving of the emission beams of light; and a processing circuit to process the detected emission beams of light for purposes of assaying a biological sample contained in each scanned well.
