Spectrum modulation-based field of view extension in Airy-beam tomographic microscopy

Abstract

We reveal the self-accelerating performance of an Airy beam under space-variable spectrum modulation, which corresponds to the extension of the field of view (FOV) and imaging depth in Airy-beam tomographic microscopy (ATM), resulting in the decline of fidelity and resolution of a reconstructed image with an increased FOV and depth of field (DOF). A strategy of spectrum modulation is proposed, and high-fidelity, high-resolution 3D imaging is realized in a 150 µm × 50 µm × 12 µm volume. This study offers a paradigm to improve the quality of reconstructed 3D images based on spectrum modulation for other light fields.
