Calculating Point Spread Functions: Methods, Pitfalls and Solutions
Ratsimandresy Holinirina Dina Miora, Erich Rohwer, Martin Kielhorn +3
The knowledge of the exact structure of the optical system PSF enables a high-quality image reconstruction in fluorescence microscopy. Accurate PSF models account for the vector na…
Generalized spectral phase-only time-domain ptychographic phase reconstruction applied in nonlinear microscopy
George Dwapanyin, Dirk Spangenberg, Alexander Heidt +4
Nonlinear microscopy has evolved over the last few decades to become a powerful tool for imaging and spectroscopic applications in biological sciences. In this study, IPIE, a n…
Implementation of temporal ptychography algorithm, IPIE, for improved single-beam coherent anti-Stokes Raman scattering measurements
Ruan Viljoen, Pieter Neethling, Dirk Spangenberg +4
We present an improvement on the signal-to-background of single-beam coherent anti-Stokes Raman scattering (SB-CARS) spectroscopy measurements for systems employing ultrafast super…
Measurement of complex supercontinuum light pulses using time domain ptychography
Alexander M. Heidt, Dirk-Mathys Spangenberg, Michael Brügmann +2
We demonstrate that time-domain ptychography, a recently introduced ultrafast pulse reconstruction modality, has properties ideally suited for the temporal characterization of comp…
All optical implementation of a time-domain ptychographic pulse reconstruction set-up
Dirk-Mathys Spangenberg, Michael Brügmann, Erich Rohwer +1
An all optical implementation of pulse reconstruction using time-domain ptychography is demonstrated showing excellent results. Setup and reconstruction are easy to implement and a…
Ptychographic ultrafast pulse reconstruction
D. Spangenberg, E. Rohwer, M. H. Brügmann +1
We demonstrate a new ultrafast pulse reconstruction modality which is somewhat reminiscent of frequency resolved optical gating but uses a modified setup and a conceptually differe…
