This is a really cool system, I wish I had time on my hands to make one. You can imagine the fiber optic cables getting tangled up. An opportunity for someone to develop a rotary joint to bring out the data, to a blue-tooth arrangement outside the oven. Or maybe tiny sensors inside that send out data through the door at 94 GHz?

Hopefully, one of you reading this can point to a company that already markets such a product.
