Electronic holographic imaging through living human tissue

Not Accessible

Abstract

Electronic holography and a swept-frequency dye laser are used with the first-arriving-light method to image an absorbing object through the flesh of a human hand. Holography with living human tissue without the use of high-peak-power lasers is made possible by the high sensitivity of the CCD camera as well as its capability for making a large number of holograms in rapid succession, thus enabling the images to be combined to produce a resultant image with an improved signal-to-noise ratio.
