High-sensitivity visualization of ultrafast carrier diffusion by wide-field holographic microscopy
Sketch of the imaging and holographic part of the transient holographic microscope, including the trains of pulses to illustrate the signal modulation approach. The array of diffraction limited excitation spots is created by imaging a pinhole array at the sample position, enabling simultaneous acquisition of transient data around 100 excitation spots.
