Fast Inertia-Free Volumetric Light-Sheet Microscope
2017
Fast noninvasive three-dimensional (3D) imag-ing is crucial for quantitatively studying highly dynamic events ranging from flow cytometry to developmental biology. Light-sheet microscopy has emerged as the tool-of-choice for 3D characterization of rapidly evolving systems. However, to obtain a 3D image, either the sample or parts of the microscope are moved, limiting the acquisition speed. Here, we propose a novel inertia-free light-sheet-based scheme for volumetric imaging at high temporal resolution. Our approach comprises a novel combination of an acousto-optic scanner to produce tailored illumination and an acoustic-optofluidic lens, placed in the detection path to provide extended dept…
Dual-beam confocal light-sheet microscopy via flexible acousto-optic deflector
2019
Confocal detection in digital scanned laser light-sheet fluorescence microscopy (DSLM) has been established as a gold standard method to improve image quality. The selective line detection of a complementary metal-oxide-semiconductor camera (CMOS) working in rolling shutter mode allows the rejection of out-of-focus and scattered light, thus reducing background signal during image formation. Most modern CMOS have two rolling shutters, but usually only a single illuminating beam is used, halving the maximum obtainable frame rate. We report on the capability to recover the full image acquisition rate via dual confocal DSLM by using an acoustooptic deflector. Such a simple solution enables us t…
Removing striping artifacts in light-sheet fluorescence microscopy: a review
2022
Abstract In recent years, light-sheet fluorescence microscopy (LSFM) has found a broad application for imaging of diverse biological samples, ranging from sub-cellular structures to whole animals, both in-vivo and ex-vivo, owing to its many advantages relative to point-scanning methods. By providing the selective illumination of sample single planes, LSFM achieves an intrinsic optical sectioning and direct 2D image acquisition, with low out-of-focus fluorescence background, sample photo-damage and photo-bleaching. On the other hand, such an illumination scheme is prone to light absorption or scattering effects, which lead to uneven illumination and striping artifacts in the images, oriented…
