A simplified approach for tomographic diffractive microscopy

Résumé

Tomographic diffractive microscopy (TDM) is an imaging technique, which allows for recording the refractive index of unlabelled transparent specimens. Based on diffraction theory, it can be implemented in transmission or in reflection. In this paper, a new TDM data acquisition and reconstruction method is proposed. The purpose is to use the mirror effect of a reflecting material to establish a double illumination system. Neglecting backward-diffracted fields, the setup reduces to a double-transmission TDM, which combined with an azimuthal rotation of the illumination, allows for faster and simplified acquisitions. We also point out a new demodulation method based only on Fourier transforms.
