Intensity interferometry-based 3d imaging

Nettet12. jan. 2024 · Imaging of cells is a challenging problem as they do not appreciably change the intensity of the illuminating light. Interferometry-based methods to do this … NettetOur reconstruction approach consists of two stages: bin-filling stage and hole-filling stage. Each pixel in the B-scan images is traversed and its intensity value is assigned to its nearest voxel in the bin-filling stage. For the efficient and accurate reconstruction, we present a new hole-filling algorithm based on the fast marching method.

Nettetfaces. Stellar amplitude (Michelson) interferometry (SAI) was employed (very simply) in the 1920’s tomeasure afew coolstars, but thetechnique was strongly control-technology-limited. In the 1960’s, stellar intensity interferometry (SII) was employed to measure some 32 stars [13], but it was, at that time, very sensitivity-limited.
