Optoacoustic micro-tomography at 100 volumes per second

Optical coherence tomography with online visualization of more than seven rendered volumes per second.

Nearly real-time visualization of 3-D volumes is crucial for the use of optical coherence tomography (OCT) during microsurgery. With an ultrahigh speed spectral domain OCT coupled to a surgical microscope, on-line display of 7.2 rendered volumes at 87 megapixels per second is demonstrated. Calculating the A-scans from the spectra is done on a quad-core personal computer (PC), while dedicated so...

100 MBit per Second VLSI Implementation of Sliding Window Coding

Multispectral Optoacoustic Tomography ( MSOT ) at 64 , 128 and 256 channels

Micro Fourier Transform Profilometry (μFTP): 3D shape measurement at 10, 000 frames per second

Recent advances in imaging sensors and digital light projection technology have facilitated a rapid progress in 3D optical sensing, enabling 3D surfaces of complex-shaped objects to be captured with improved resolution and accuracy. However, due to the large number of projection patterns required for phase recovery and disambiguation, the maximum fame rates of current 3D shape measurement techn...

High-speed 1310 nm-band spectral domain optical coherence tomography at 184,000 lines per second.

We propose a useful method to boost the imaging speed for spectral domain optical coherence tomography (SDOCT) by multiplying a number of high-speed spectrometers used in the system with selective precise control of data-recording and data-reading phases for spectral cameras employed in each spectrometer. To demonstrate the proposed method, we use two spectrometers built in a 1310 nm-band SDOCT...
