Mirror-assisted tomographic diffractive microscopy with isotropic resolution

摘要

We demonstrate that the axial resolution of a reflection tomographic diffractive microscope is drastically improvednwhen the sample is placed in front of a perfect mirror.We show analytically and with rigorous simulations that thisnapproach permits us to obtain images with the same isotropic resolution as that obtained when the sample is illu-nminated and observed fromevery possible angle. Themain difficulty lies in accounting properly for themirror in theninversion algorithm. © 2010 Optical Society of America
