A new holographic technique, called phase-modulated holography (PMH), has been developed. With this method, amplitude and phase gratings generated by photochemical or photophysical changes of molecules dissolved in, e.g. solid matrices, can be monitored separately and simultaneously. Accordingly, the hologram formation mechanism and the underlying photoreaction can be monitored separately and simultaneously allowing conclusions to be made on photoinduced matrix effects and direct measurements of photochemical quantum yields. This feature and an up to eight orders of magnitude improvement of detection sensitivity over conventional phase-insensitive holographic techniques makes PMH the ideal tool for the investigation of new holographic recording materials and of photochemistry and photophysics of molecules in the condensed phase.
