Optical volume control for theremin

[Ghode]

Hi! I'm new at the forum....I'm actually building an optical theremin based on the negistor oscillator which sounds great, and I want to add to it an optical volume control but I can't seem to find any info on it...Any ideas on this???

Wish I could help, but my experience with optical is limited to playing with photo resistors when I was a kid. I found this forum which might help:
