摘要：
A method of obtaining PINEM images includes providing femtosecond optical pulse, generating electron pulses, and directing the electron pulses towards a sample. The method also includes overlapping the femtosecond optical pulses and the electron pulses spatially and temporally at the sample and transferring energy from the femtosecond optical pulses to the electron pulses. The method further includes detecting electron pulses having an energy greater than a zero loss value, providing imaging in space and time.
