Handling negative patterns for fast single-pixel lifetime imaging

A group of researchers working in France and USA, leaded by N. Ducros, has uploaded an interesting paper this week. When doing single-pixel imaging, one of the most important aspects you need to take into account is the kind of structured patters (functions) you are going to use. This is quite relevant because it is …

Wavefront correction in two-photon microscopy with a multi-actuator adaptive lens

The group leaded by P. Artal at Murcia University has recently published an interesting paper related to adaptive optics using an adaptive lens. When working in a real scenario, imperfections in the optical elements you use or just the objects you want to image introduce optical aberrations in the pictures you obtain. Usually these aberrations reduce …

Weekly recap (29/04/2018)

This week we have a lot of interesting stuff: Observing the cell in its native state: Imaging subcellular dynamics in multicellular organisms Adaptive Optics + Light Sheet Microscopy to see living cells inside the body of a Zebra fish (the favorite fish of biologists!). Really impressive images overcoming scattering caused by tissue. You can read …

The week in papers (22/04/18)

As a way to keep posts going, I am starting a short recap about interesting papers being published (or being discovered) every now and then. Probably I will write longer posts about some of them in the future. Let's get this thing going: Two papers using 'centroid estimation' to retrieve interesting information: Extract voice information …

Kilohertz binary phase modulator for pulsed laser sources using a digital micromirror device

People at Judkewitz lab tend to do really cool stuff. This time they have implemented a binary phase modulator using a DMD. Kilohertz binary phase modulator for pulsed laser sources using a digital micromirror device, M. Hoffmann et al, at Optics Letters Abstract: The controlled modulation of an optical wavefront is required for aberration correction, …

Light transport and imaging through complex media & Photonics West 2018

Last ~20 days have been completely crazy. First, I went to a meeting organized by the Royal Society: Light transport and imaging through complex media. It was amazing. Beautiful place, incredible researchers, and a nice combination of signal processing and optical imaging. I am sure I will be looking for future editions. After that, I assisted …
