Abstract
A frequency-chirped optical pulse provides a natural mapping between time and wavelength. We propose to utilize this correspondence to impress the time-dependence of transmissivity of a sample cell onto the spectrally-varying intensity of a frequency-chirped optical probe. The time-dependent transmissivity encoded this way would then be subsequently recovered from the time-integrated spectrum of the probe. Retaining one dimension of spatial resolution, the technique would produce an optical streak camera of potentially very high time resolution (better than 200 fs); other modifications would produce an optical framing camera having frame times less than 10 ps. Application is not limited to the optical regime: use with x rays is discussed, along with applications to different optical sample cells and detector cells.
