At lower frame rates, the latency between a fly moving and the laser adjusting can lead to "misses." By pushing our image processing and control logic to 120fps , we reduce this lag significantly. This allows for sub-0.2mm precision, ensuring that the light or heat is applied exactly where intended, whether that's the thorax or the head.
: 2D galvanometers used to aim lasers at specific body regions of freely walking flies.
: Two cameras (wide-field for tracking and high-magnification for targeting). bj-full-120fps.mp4

This video file refers to technical documentation from (the Fly Mind Altering Device), an open-source hardware system developed for real-time tracking and optogenetic/thermogenetic stimulation of fruit flies. The "120fps" in the filename highlights the system's capability to process image data at high speeds for precise targeting. 🔬 Project Overview: FlyMAD
