Abstract

The space-bandwidth product (SBP) is the product between the field of view (FOV) and the spatial frequency range, that is, the maximum number of resolvable point spread function (PSF) in the FOV. Establishing a high SBP system by achieving both high resolution and a wide field of view is hindered by optical diffraction, geometric aberrations, size limitations, and thermal effects, since these factors collectively limit the attainable resolution and field of view. In this study, the SBP is maximized by using the off-the-shelf high throughput lens which provides large FOV (8.1 mm) and submicron resolution (700 nm) for an effective SBP of 0.3 gigapixels. The deterioration in resolution caused by aberrations from the large aperture of the objective lens is compensated by applying adaptive optics with correcting the distorted wavefront. Galvanometer scanners transfer information to a single fixed camera to achieve a large FOV. Our method does not have any moving parts or any requirements on postprocessing enabling fast high resolution imaging across large FOVs.
