Zusammenfassung:
We demonstrate an implementation of frequency-encoded photocurrent spectroscopy using a super-continuum light source. The spectrally broad light is spatially dispersed and modulated with a special mechanical chopper design that permits a continuous wavelength-dependent modulation. After recombination, the light beam contains a frequency encoded spectrum which enables us to map the spectral response of a given sample in 60 ms and with a lateral resolution of 10 μm.
Helpful discussions with Daniel Molter, Frank Ospald, and Jens Klier are gratefully acknowledged. This work was supported by the FhG internal programs (Attract grant 692247).
