Very wide-field of view imaging can provide statistical data on large cell populations in a single acquisition. In this paper, we describe a multimodal imaging system combining brightfield, phase and fluorescence contrasts. Its greater simplicity and lower cost compared to flow cytometry make it suitable for Point-Of-Care applications. The system’s resolution was characterized on calibrated beads and resolution targets. We illustrate the potential of the single-shot imaging approach in hematology by studying the specific morphologies of white blood cell sub-types. The results suggest that very wide field of view imaging could be an alternative to flow cytometry for some applications in hematology.
