Abstract
An electronic imaging flow-microscope for remote environmental sensing, bioreactor process monitoring, and optical microscopic tomography applications is described. A fluid conduit has a port on each end of a thin flat transparent fluid transport region. A planar illumination surface contacts one flat side of the transparent fluid transport region and a planar image sensing surface contacts the other flat side. Light from the illumination surface travels through the transparent fluid transport region to the planar image sensing surface, producing a light field affected by the fluid and objects present. The planar image sensing surface creates electrical image signals responsive to the light field. The planar illumination surface can be light emitting elements such as LEDs, OLEDs, or OLET. whose illumination can be sequenced in an image formation process. The flow microscope can further comprise flow-restricting valves, pumps, energy harvesting arrangements, and power management.
