The power spectrum thus translated into the visible region can be readily measured with a standard silicon CCD camera-based spectrometer. The spectral phase is also characterized by a variant of zero-added-phase spectral phase interferometry for direct electric field reconstruction. This is a general method that provides a multiplex advantage over conventional infrared detector array-based methods. © 2005 Optical Society of America %G English %2 https://polytechnique.hal.science/hal-00829235/document %2 https://polytechnique.hal.science/hal-00829235/file/ol-30-10-1228.pdf %L hal-00829235 %U https://polytechnique.hal.science/hal-00829235 %~ INSERM %~ X %~ CNRS %~ X-LOB %~ X-DEP %~ X-DEP-BIO
