Fig. 2. Structured light source for segment-specific illumination of Drosophila larvae.

Fig. 2

a Sketch of the experimental setup (side view) and b of the larva mounted on top of the OLED and inside the PDMS channel (top view). c Photograph of a larva mounted in a PDMS channel on top of a microstructured OLED. d Exemplary images used to estimate the spatial resolution of photostimulation from the profiles of scattered light at the top side of the larva; blue line: extracted emission profile (width: 37 px); the arrow points to the active pixel. e Profiles taken during illumination of different abdominal segments. The blue shaded area marks the 100 µm wide OLED pixel. Scale bars in c and d: 1 mm.
