Abstract
A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated and an optical state detector. The optical state detector obtains electromagnetic radiation from the internal volume while the internal volume is EMI isolated and makes a determination that a device disposed in the internal volume has an optical state associated with the electromagnetic radiation.
