Fourier light field microscopy (FLFM) captures a sample 3D volume in a single snapshot, providing game-changing imaging speed for various bio-imaging applications. Existing FLFM platforms have often been designed as single-purpose implementations, with a fixed performance in resolution and field of view, restricting widespread applications. Here, to democratize FLFM toward broader adoption for biomedical research, we describe a multi-purpose implementation of FLFM that enables synchronous volumetric imaging across a wide range of resolution and field of view. With our single instrument, we demonstrate a variety of bio-imaging applications across scales, including sub-cellular dynamics, tissue cellular dynamics, and whole-brain neural activity.
