Abstract
We have recently (BOE July 2022) proposed an interferometric approach called full-field transmission tomography (FFOTT) based on the use of the Gouy phase shift that manifests at the focus of microscope objectives. Forward scattering of cellular structures larger than 100 nm being much greater than backscattering (used in OCT) performances constraints of the imaging system are strongly relaxed and setups using cheap microscopes and a smartphones become possible. Note that good quality 100X, NA+1.25 objectives are available for less than $100. We show cells and tissues images through their morphological or metabolic contrasts modified by a chemical or biological environments.
