Spatial, spectral, and polarization multiplexed ptychography.
We introduce a novel coherent diffraction imaging technique based on ptychography that enables simultaneous full-field imaging of multiple, spatially separate, sample locations. This technique only requires that diffracted light from spatially separated sample sites be mutually incoherent at the detector, which can be achieved using multiple probes that are separated either by wavelength or by ...
متن کاملComputational time-resolved imaging
Classical photography uses steady-state illumination and light sensing with focusing optics to capture scene reflectivity as images; temporal variations of the light field are not exploited. This thesis explores the use of time-varying optical illumination and time-resolved sensing along with signal modeling and computational reconstruction. Its purpose is to create new imaging modalities, and ...
متن کاملDynamic imaging using ptychography.
We demonstrate through experiment an example of "mixed state" reconstruction using x-ray ptychography. We demonstrate successful imaging of a vibrating sample that has dynamics that are of one order magnitude faster than the measurement times. We show how increased vibrational amplitude leads to an increased population of illumination modes, a characteristic of partial coherence. Implications o...
متن کاملDissociative multiphoton ionization of NO2 studied by time-resolved imaging.
We have studied dissociative multiphoton ionization of NO2 by time-resolved velocity map imaging in a two-color pump-probe experiment using the 400 and 266 nm harmonics of a regeneratively amplified titanium-sapphire laser. We observe that most of the ion signal appears as NO+ with approximately 0.28 eV peak kinetic energy. Approximately 600 fs period oscillations indicative of wave packet moti...
متن کاملTime Resolved Lung Ventilation Imaging by Fourier Decomposition
Results and Discussion: In summary, we have shown that MR ventilation imaging is possible without any exogen means like polarized gases, oxygen administration or contrast media. The very fast protocol and simple post processing technique allows the selective depiction of blood, stationaryand shifted tissue, it shows promise to improve the diagnosis of pulmonary diseases. The elegance of the Tru...
