Abstract
An arrangement of one or more micro cameras are used in conjunction with computer controlled illumination to create a high-throughput microscope able to operate without the need of expensive scanning stages. A single unit contains a plurality of sensors, lenses tiled in such a way to cover a significant fraction of the desired field of view in a digital single acquisition. Mechanical stages and patterned illumination can then be used in conjunction with the system to enhanced the imaged depth of field, or create an acquisition stack to enhance the information acquired. Multiple units can be combined to obtain images of a single sample from different angles. The absence of mechanical stages makes the imaging system ideal for use in scenarios that require the sample to be in a climate and/or environmentally controlled chamber.
