What is possible with holographic endoscopy? (Invited Paper)

Endoscopic holography or endoholography combines the features of endoscopy and holography. It can be utilized in holographic imaging or interferometry inside natural cavities of the body. In imaging, the ability to view a three-dimensional, large focal depth, faithful rendition of internal organs and tissue may greatly enhance the detection of disease and abnormality. Contact Denisyuk holography makes it possible to obtain a high-resolution holographic recording which can be examined microscopically. In the case of endoholographic interferometry, new diagnostic techniques can emerge; e.g., the measurement of compliance of the wall of the bladder or of the arteries may provide diagnostic indicators of early stages of disease.
