Fast focus field calculations
Theo Lasser, Marcel Leutenegger, Rainer Leitgeb, Ramachandra Rao
We present a fast calculation of the electromagnetic field near the focus of an objective with a high numerical aperture (NA). Instead of direct integration, the vectorial Debye diffraction integral is evaluated with the fast Fourier transform for calculat ...
2006Tomography using multiple wavelengths in digital holographic microscopy
This thesis presents a new tomographic imaging method using multiple wavelengths in digital holographic microscopy. It is based on the addition of several reconstructed wavefronts measured at different wavelengths. The resulting diffraction tomographic vis ...
EPFL2006Measurement and interpretation of the 3D amplitude point spread function of lenses and microscope objectives
The intensity point spread function (IPSF) is most often used to characterize optical imaging systems. For some imaging applications such as digital holographic microscopy the 3D amplitude point spread function (APSF) more completely describes an optical s ...
