Projector

For visual stimulation, we use a FL35 LED DLP projector from Projection Design. The current installation runs at 32 bit color in 1920*1080 @ 120 fps.. Maximum field of view for visual presentation is about 63 (horizontal) * 41 (vertical) degrees.

In standard settings (16:9 ratio, 1920x1080 resolution, 120 fps, 100 cm distance), the projector fills a 72 x 44 cm rectangle on the screen, ca 40 x 25 degrees of the visual field.

Presenting a white picture on the screen gives 100 lumen on screen, 30 lumen at eye position.

The visual stimulation is typically controlled via Neurobs Presentation, in which case the computer-to-eye delay is about 8 ms, with no frame drops or frame doubles.
