Oblique plane microscopy (OPM) provides high spatiotemporal resolution, but the field of view is typically limited by its optical train and the pixel number of the camera. Mechanically scanning the sample or decreasing the overall magnification of the imaging system can partially address this challenge, albeit by reducing the volumetric imaging speed or spatial sampling, respectively. In this Letter, we introduce a novel dual-axis scan unit for OPM that enables rapid and high-resolution volumetric imaging throughout a volume of 800 × 500 × 200 microns. This enables imaging of model organisms, such as zebrafish embryos, with subcellular resolution. Furthermore, we combined this microscope with a real-time and multi-perspective projection imaging technique to increase the volumetric interrogation rate to more than 10 Hz.Competing Interest StatementThe authors have declared no competing interest.
