PDF Link In off-axis interferometry, we usually have to deal with the unwrapping process, which is very computationally intensive and prevents us from real time phase reconstruction. The wrapping problem usually occurs when imaging thick objects, which introduce phase shifts of more than 2π radians. However, in off-axis interferometry, the nonzero angle of interference of […]

T. Kim et al. Gradient field microscopy for label-free diagnosis of human biopsies, Appl. Opt. (Special Issue on Holography), 52 (1), A92-A96 (2013)

PDF Link We introduce a label-free method for detecting high-grade prostatic intraepithelial neoplasia (HGPIN) in unstained biopsies. We image this condition based on the identification of basal cells in biopsies that otherwise would resemble prostate cancer by unassisted histologic examination. Gradient field microscopy (GFM) is used as a label-free imaging method which increases the contrast […]
