Excerpt from the research highlights of the working group

Since the foundation of the research group around Robert Huber in 2007, numerous milestones have been set in research around FDML lasers, OCT imaging or nonlinear optics. Among them are not only research-related events but also technological leaps that should be mentioned here.

General

James G. Fujimoto, Eric A. Swanson & Robert Huber - High resolution medical imaging

2017


Optical coherence tomography

First VR-OCT-guided ex vivo surgery on a swine eye

2019

OCT video of human retina

2015

The video displays an OCT recording of a human retina. It was recorded at a volume rate of 20.8 V/s and consists of 255x255x450 voxels. Intentional movements of up to 100°/s are resolved.

High definition live 4D-OCT in vivo: Triops

2014

The video was acquired and processed in real time. The OCT system uses a 1310 nm Fourier domain mode locked (FDML) laser operated at 3.2 MHz sweep rate. The acquired data was processed and visualized on a GPU [10.1364/BOE.5.002963].

High definition live 4D-OCT in vivo for surgical guidance

2014

The video was acquired and processed in real time. The OCT system uses a 1310 nm Fourier domain mode locked (FDML) laser operated at 3.2 MHz sweep rate and the data was processed and visualized on a GPU [10.1364/BOE.5.002963].

3D reconstruction of intravascular OCT scan with 3200 fps

2013

A micromotor driven catheter developed in the group of Dr. Gijs van Soest in combination with our 1.6 MHz FDML-OCT surpasses the acquisition speed of state of the art intravascular OCT by more than one order of magnitude [10.1364/OL.38.001715].

Anterior segment imaging with extended coherence length MHz FDML laser

2012

OCT imaging at 60 nm sweep range and 1.6 MHz scan rate. The 3D reconstruction of the whole anterior segment consisting of 1000 x 985 x 560 voxels (frames x depth scans x samples/scan) was acquired in a total time of 0.8 seconds [10.1364/BOE.3.002647].

Anterior segment imaging with extended coherence length MHz FDML laser

2012

The 3D reconstruction of the whole anterior segment consisting of 1000 x 900 x 560 voxels (frames x depth scans x samples/scan) was acquired in a total time of 0.8 seconds [10.1364/BOE.3.002647].

High quality 3D imaging at 20 million A-scans and 4.5 GVoxels per second

2010

This three dimensional dataset was acquired in 25ms. This was accomplished by using a FDML laser with a sweep rate of 5.2 MHz per spot and a 4-spot illumination [10.1364/OE.18.014685].
