Time-integrated holography and optical tomography

Optical tomography and digital holography

Optical tomography for biomedical applications by digital interference holography

We present results of imaging experiments using digital interference holography (DIH). Calibration experiments using a resolution target demonstrate an improvement of signal-to-noise ratio (SNR) with increasing number of holograms consistent with theoretical prediction. Imaging experiments on retinal tissue reveal the topography of blood vessels as well as the optical thickness profile of the r...

Integrated diffuse optical tomography and photoacoustic tomography: phantom validations

We designed, fabricated and tested a novel imaging system that fuses diffuse optical tomography (DOT) and photoacoustic tomography (PAT) in a single platform. This platform takes advantages of both DOT and PAT, and can potentially provide dual-modality two dimensional functional and cellular images of the breast quantitatively. Here we describe this integrated platform along with initial tissue...

All-optical wavelength conversion based on time-domain holography.

All-optical wavelength conversion of a complex (amplitude and phase) optical signal is proposed based on an all-optical implementation of time-domain holography. The temporal holograms are generated through a cross-phase modulation (XPM) process in a highly-nonlinear optical fiber, avoiding the necessity of accomplish the phase matching condition between the involved pump and probe signals, and...
