Increasing the spatial bandwidth product in light field microscopy with remote scanning.

Abstract

Achieving fast, large-scale volumetric imaging with micrometer resolution has been a persistent challenge in biological microscopy. To address this challenge, we report an augmented version of light field microscopy, incorporating a motorized tilting mirror upstream of the camera. Depending on the scanning pattern, the field of view and/or the lateral resolution can be greatly improved. Our microscope technique is simple, versatile, and configured for bright-field and epifluorescence modes. We demonstrate its performance with imaging of multi-cellular aggregates of various shapes and sizes.
