Abstract: A micro-plate reader for use with a portable electronic device having a camera includes an opto-mechanical attachment configured to attach/detach to the portable electronic device and includes an array of illumination sources. A slot in the opto-mechanical attachment is dimensioned to receive an optically transparent plate containing an array of wells. Optical fibers are located in the opto-mechanical attachment and transmit light from each well to a reduced size header having, wherein the fiber array in the header has a cross-sectional area that is ≤10× the cross-sectional area of the wells in the plate. A lens located in the opto-mechanical attachment transmits light from the header fibers to the camera. Software executed on the portable electronic device or other computer is used to process the images to generate qualitative clinical determinations and/or quantitative index values for the separate wells.

Abstract: A system for measuring chlorophyll concentration in a leaf sample includes a leaf-holding illuminator device with a main body containing a power source, a plurality of switchable light sources emitting light at different spectra (e.g., red and white light from a broadband light source), and a cap detachably secured to the main body using one or more fastening means. The leaf sample is interposed between the main body and the cap and held in place during imaging. The system includes a mobile electronic device having a camera configured to capture an image of the leaf illuminated by the plurality of switchable light sources, the mobile electronic device having wireless connectivity to a network and an application contained therein configured to transfer the images to a remote sever or computer via the network for data processing. A final chlorophyll index value is calculated based on the transferred images.
