Heterodyne Fourier domain optical coherence tomography for full range probing with high axial resolution

Adrian Bachmann, Theo Lasser, Rainer Leitgeb

One of the main drawbacks of Fourier domain optical coherence tomography (FDOCT) is the limited measurement depth range. Phase shifting techniques allow reconstructing the complex sample signal resulting in a doubled depth range. In current complex FDOCT r ...

Fast focus field calculations

Marcel Leutenegger, Theo Lasser, Ramachandra Rao, Rainer Leitgeb

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 ...

Dual-color total internal reflection fluorescence cross- correlation spectroscopy

Marcel Leutenegger, Theo Lasser, Rainer Leitgeb

We present the development and first application of a novel dual-color total internal reflection (TIR) fluorescence system for single-molecule coincidence analysis and fluorescence cross-correlation spectroscopy (FCCS). As a performance analysis, we measur ...

Extended focus depth for Fourier domain optical coherence microscopy

Adrian Bachmann, Theo Lasser, Lukas Steinmann, Martin Villiger, Rainer Leitgeb

We report on a new detection scheme for Fourier domain optical coherence microscopy that exhibits high transverse resolution along an axially extended focal range. Nearly constant transverse resolution of ∼1.5 μm along a focal range of 200 μm is experiment ...
