Claim:
1. An optical microscope comprising: an objective lens for receiving and collimating optical spectrum electromagnetic radiation emitted or scattered from an object of interest; a volume hologram with a plurality of multiplexed holographic gratings to receive and diffract the collimated optical spectrum electromagnetic radiation, each of the plurality of multiplexed holographic gratings being Bragg matched to diffract optical spectrum electromagnetic radiation corresponding to a different depth in the object of interest; a relay system to receive and relay the diffracted collimated optical spectrum electromagnetic radiation from the volume hologram corresponding to the different depths in the object of interest; a phase filter to receive and simultaneously filter the relayed collimated optical spectrum electromagnetic radiation from each of the different depths in the object of interest; and a focusing lens to focus onto an imaging plane the collimated optical spectrum electromagnetic radiation that passes through the phase filter simultaneously forming a plurality of filtered two-dimensional images of the object of interest each corresponding to one of the different depths in the object of interest, wherein the phase filter is located at the relayed conjugate plane of the volume hologram's pupil.
