The intensity and phase of one or more ultrashort light pulses are obtained using a non-linear optical medium. Information derived from the light pulses is also used to measure optical properties of materials. Various retrieval techniques are employed. Both "instantaneously" and "non-instantaneously"...http://www.google.es/patents/US5530544?utm_source=gb-gplus-sharePatente US5530544 - Method and apparatus for measuring the intensity and phase of one or more ultrashort light pulses and for measuring optical properties of materials
