Volume Holography, Multidimensional Visualization, Confocal Microscopy.


The use of volume holograms as spatially and spectrally selective imaging elements in a microscope system is presented. By multiplexing several gratings in the same volume, the holographic microscope is able to extract in a single measurement 4-D information (3-D spatial plus color) of a specimen, making the instrument well suited for applications that demand real-time visualization of an object. The operation of the device is experimentally demonstrated.
