We demonstrate fluorescent imaging flow-cytometry that is integrated on a cell-phone. The cellphone based flow-cytometer was used to measure the density of white-blood-cells in blood samples, providing a decent match to the hematology analyzer.
We demonstrate a telemedicine microscopy platform which operates based on lens free digital holography. It utilizes an incoherent light-source and an opto-electronic sensor-array to record lens free holograms of micro-objects within a sample, which are then rapidly processed using custom-developed algorithms to provide microscopic images of the samples without the use of any lenses, lasers or other...
We demonstrate wide-field fluorescent imaging on a cell-phone, using compact and cost-effective optical components that are mechanically attached to the existing camera unit of the cell-phone. Battery powered light-emitting diodes (LEDs) are used to side-pump the sample of interest using butt-coupling. The pump light is guided within the sample cuvette to excite the specimen uniformly. The fluorescent...
We report a field-portable lensless on-chip microscope with a lateral resolution of <1μm and a large field-of-view of ∼24mm2. This microscope is based on digital in-line holography and a pixel super-resolution algorithm to process multiple lensfree holograms and obtain a single high-resolution hologram. In its compact and cost-effective design, we utilize 23 light emitting diodes butt-coupled to...
