Measurement depth enhancement in terahertz imaging of biological tissues
Optics Express, 2013 We demonstrate the use of a THz penetration-enhancing agent (THz-PEA) to enhance the terahertz (THz) wave penetration depth in tissues. The THz-PEA is a biocompatible material having absorption lower than that of water, and it is easily absorbed into tissues.

Choroidal Mapping; a Novel Approach for Evaluating Choroidal Thickness and Volume
Journal of Ophthalmic & Vision Research, 2012 There are a limited number of non-invasive imaging techniques available for assessing the choroid, a structure that may be affected by a variety of retinal disorders or become primarily involved in conditions such as polypoidal choroidal vasculopathy and

Single exposure 3D imaging of dusty plasma clusters
, 2012 We have worked out the details of a single camera, single exposure method to perform three-dimensional imaging of a finite particle cluster. The procedure is based on the plenoptic imaging principle and utilizes a commercial Lytro light field still ...
