Much thanks for that update explaining the gain circuit! I origionally had the slitted-shotgun approach you had on your webpage, but that was picking up reflections, so I thought I'd try the full shotgun approach, and when that didn't work, I added some translucent material to the end... I see now that I was only making it worse and worse - less ambient light got to the sensors, so they fired their sensitivity all the way up and picked up even fainter reflections. Went back to the slitted shotgun but with a desk lamp shining on it, and it works beautifully. Again, thanks for the information.
