Hi everyone

Hi, this is Kevin.  I’ve been doing a little work with the detector, chopper, and infrared source.  I’m currently trying to show how good the detector works when its not pointed directly at the source and when it gets further and further away.  Here are some pictures of the setup:

This would be a good graph, except for a one thing, maybe more, but I hope not.  Can anyone figure out whats wrong? (hint: its also a term for a penalty in football, the real football, not soccer)
