In general, what's the difference between the IR "signal" that the
tower and RCX use to communicate and the IR energy used in thermal
imaging? Is it just a matter of frequency? If the RCX was pointed at
an IR camera, what what would it see?

| Typical remote control IRs like the RCX system are usually in the 870 - 950 nm range, just below visible red. A standard silicon CMOS camera chip will "see" this fine unless it has an IR cut filter (commonly installed in camcorders etc). Silicon is (...) (23 years ago, 14-May-02, to lugnet.robotics)

IR sensors (of the type used by the military for night operations for example) operate over some fixed range of IR frequencies - some work in the near IR (or perhaps even somewhat into the Red end of the visible spectrum) - others in the far (...)
