Hey guys, I am trying to come up with an idea to measure incident intensity of headlights from an oncoming car for one of my uni projects. This wasn't specifically assigned project topic, we get to choose what we want to do. It's my Instrument and Measurement unit, and I had this idea thought it would have an interesting application considering how many times I have driven on the freeway and just got completely blinded by an oncoming (or following) car. We've learned of different methods of measurement like an LDR (Photoresistor) in a voltage divider and calibrating a micro controller to give you readings in Lux. But I was wondering how one could roughly go about measuring a specific car's headlight by pointing the device at it and filtering out some of the other light 'noise' so to speak? I'm thinking something akin to a pinhole camera, sort-off? Any Suggestions? Thanks in advance!
