Parallel Fourier ptychographic microscopy for high-throughput screening with 96 cameras (96 Eyes).

ABSTRACT: We report the implementation of a parallel microscopy system (96 Eyes) that is capable of simultaneous imaging of all wells on a 96-well plate. The optical system consists of 96 microscopy units, where each unit is made out of a four element objective, made through a molded injection process, and a low cost CMOS camera chip. By illuminating the sample with angle varying light and applying Fourier Ptychography, we can improve the effective brightfield imaging numerical aperture of the objectives from 0.23 to 0.3, and extend the depth of field from ±5 μm to ±15 μm. The use of Fourier Ptychography additionally allows us to computationally correct the objectives' aberrations out of the rendered images, and provides us with the ability to render phase images. The 96 Eyes acquires raw data at a
