Rainbow volume holographic imaging.
We present a new form of volume holographic imaging with rainbow illumination. High depth resolution is obtained because each quasi-monochromatic band of the rainbow acts as a depth-selective confocal slit. The color slits work in parallel to achieve a wide field of view (FoV) and so the need to scan in one lateral dimension is eliminated. Our experiments demonstrated <250-micro m depth resolution over an approximately equal to 15 degree FoV at a 50-mm working distance.
