In this preprint, Stirman et al. report achieving a 3.5 mm field of view with 2-photon excitation with cellular resolution. The design involves custom scan optics and a custom objective built in the…
Lightfield imaging – development kit from Lytro
Posted in Hardware
Lytro is releasing a development kit for their light field camera. That’s nice, but it pretty expensive. And we’ve been able to buy light field cameras for technical uses for years.

Rolling shutter vs. global shutter: why it matters
Digital cameras can have global shutters or rolling shutters (some cameras can operate in both modes). Global shutters are preferable for periodic applications, including intrinsic imaging, because rolling shutters can cause artifacts. This article does a nice job of explaining the artifacts…
Resonant scanning with ScanImage 5
Posted in Hardware
ScanImage 5 supports resonant scanning with a wide range of hardware. So custom rigs can add resonant scanning pretty easily, while sticking with ScanImage for acquisition.
It takes about $10,000 worth of electronics…
