Sourcing scan mirrors in early 2022
Posted in Hardware
There are some companies that have no real competition. Maybe a product here-and-there in their catalog is subject to market forces, but most of their items have no competing options from other…
Guidance for designing an objective from scratch
Several people have reached out for guidance on designing and building an objective from scratch, when they have little-to-no background in custom optics. Here are some notes on the topic, in broad strokes, focused on the practicalities.

Open, easy laser-scanning microscope software: LSMAQ
Posted in Software
Years ago, Benjamin Judkewitz wanted to try some new techniques out with laser scanning two-photon microscopy. However, the software we were using was rather cumbersome to modify. So he wrote his own software from…
A resonant-galvo-galvo module from Vidrio/ScanImage
Posted in Hardware
This could be handy for some of you. Resonant scanners are fast, but inflexible. You can’t tell them where to go. They just oscillate at a fixed frequency. All you can do is control the…
Remote focusing with deformable mirrors
Posted in Hardware
There are lots of ways to quickly change the z-focus plane, including tunable lenses, piezo objective movers, and a coupled objective. What is the best way to change the Z-focus…

Real-time tracking and 2p imaging with sub-ms timing
Posted in Papers
In this work, the authors used fast optical motion tracking and 2p imaging to measure the activity of individual neurons in freely moving animals. No surgery. No optical window. No restraint. And all the benefits…
Using NI DAQmx in MATLAB
This post is from Rob Campbell:
As part of TENSS we have created a set of examples showing how to use DAQmx in MATLAB without the Data Acquisition Toolbox. This is…
OpenMV – Fast and easy machine vision
OpenMV is an open source machine vision system. It’s designed to be easy-to-use, with a gentle learning curve. They want this to be the “Arduino of Machine Vision”. The software IDE is…
Moire lenses
Posted in Hardware
Moiré lenses are cool: two patterned diffractive optical elements are rotated relative to each other to vary the power of the “lens”. Just watch the video (below).
Demonstration of focus-tunable diffractive Moiré-lenses

Pixy computer vision for tracking mouse behavior
Pixy is an open source computer vision system. Mostafa Nashaat, Robert Sachdev, and colleagues including Matthew Larkum have developed software for use with the Pixy, that can be used to track mouse behavior, including free movement around…
Analysis algorithms: performance quantification and ground truth
Posted in Software
We recently tweeted about a preprint from Eftychios A Pnevmatikakis and Andrea Giovannucci (code). The preprint is on motion correction for calcium imaging data. It is a nice quick read and discusses earlier work in…
