Abstract
The combination of femtosecond pulses with microscopes resolves processes at ultrashort time scales with spatial resolution. However, an integration into three-dimensional imaging methods, allowing to retrieve ultrashort processes as a function of three-dimensional space and time in complex and crowded environments, is lacking. We have achieved the implementation of broadband optical pulses with more than 100 nm bandwidth into a holographic optical diffraction tomography (ODT) setup. Besides having overcome a critical step towards ultrafast three-dimensional imaging we realized spectrally resolved ODT, retrieving the specimen’s refractive index as a function of 3D space and wavelength over the entire bandwidth.
