Description
The screen trigger device is a small optical sensor that can be mounted in the corner of a screen. It contains a photo diode with build in amplifier that senses the intensity of the screen locally. It has a BNC output that gives 0 Volt output when the screen is locally black and 5 V output when the screen is locally white. This can be used to create a digital timing signal for changes on the screen.
Design
The screen trigger devices has a TSL25xR photo sensor with build-in amplifier.
