  • 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…

  • Evading scientific stalemates

    This week I have been thinking about a strange thing that happened in my research group. One day while I was doing my MSc, me and my colleagues we were discussing some lab results. A small change on our experimental setup provided much better images than the ones we were getting up to that point.…

  • 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…

  • Optical companding

    Christmas came and gone, and I am still trying to keep up with some papers I’ve read in the last months. The guys at UCLA keep doing impressive stuff. First time I saw something from them was their work on Nature about ultrafast optical imaging (woah!). This time they have proposed a way to improve the…

  • Focusing light through dynamical samples using fast continuous wavefront optimization

    The guys at LKB keep going inside turbid media. This time, they have done it really fast. By using a phase spatial light modulator and with the help of a FPGA card, they were able to focus light through a scattering medium at a rate of ~4 kHz. This is trying to solve a common problem…
