Ophthalmic Tomography by Digital Interference Holography |
||
 |
Digital interference holography (DIH) generates 3D volume tomographic
images of tissues, such as human macular and optic nerve tissues. DIH has the potential to become a useful tool for researchers and clinicians in the diagnosis and treatment of many ocular diseases, including glaucoma and a variety of macular diseases.

Digital Holography of Total Internal Reflection |
||
 |
Quantitative phase microscopy by digital holography is used to image the phase profile of light in total internal reflection, which is modulated by the materials present on or near the surface of internal reflection. The technique can be used to study the focal adhesion of cells moving on a substrate surface.. |

Digital Holographic Microscopy |
||
 |
Quantitative phase microscopy by digital holography offers a number of unique advantages over conventional microscopy. Numerical focusing of holographic images can be accomplished from a single hologram. Direct access to the phase information facilitates numerical correction of various aberrations of the optical system, such as field curvature and anamorphism.

Biometry Applications of Digital Holography |
||
 |
Digital holographic phase microscopy can yield images of thin film latent finger prints with high sensitivity. Digital interference holography can yied 3D topographic images of finger, palm, iris, and other biometrically significant objects.
