Abstract

We performed non-invasive video imaging of retinal blood flow in a pigmented rat by holographic interferometry of near-infrared laser light backscattered by retinal tissue, beating against an off-axis reference beam sampled at a frame rate of 39 kHz with a high throughput camera. Local Doppler contrasts emerged from the envelopes of short-time Fourier transforms and the phase of autocorrelation functions of holograms rendered by Fresnel transformation. This approach permitted imaging of blood flow in large retinal vessels (30 microns diameter) over 400 by 400 pixels with a spatial resolution of 8 microns and a temporal resolution of 6.5 ms., Comment: 4 pages, 5 figures, 4 links

Abstract

“The French “yellow jackets” rallied in the streets but not in the ballot box.” Le Figaro posted after the 2019 European elections. “The two lists from the social contestation movement, which has provoked the biggest crisis of Emmanuel Macron’s five-year term, collected less than 1% of the votes in the European elections on Sunday, May 26.” The failure of the French yellow jackets to penetrate European institutions is the class of contemporary failures that forms the starting point of Dimitri...
