Heat sensing microwave oven

<span style="font-family: arial, helvetica, sans-serif;">It does sound like a good idea but I can't see it working unless the heat distribution is consistent and even. I suppose to achieve that it would have to cycle or power down automatically while the heat in the hot spots transferred across the food</span>
Could be better, more accurate than the current moisture-sensor auto cook systems if all the potential kinks are worked out.

With the RR-1 featured at the beginning of the video, you can also hear the food cooking as there's no glass in the door, ain't that a great feature too!? I think that's useful for blind people! It's also easy to set with very few buttons unlike a RR-10 which from my experience, can challenge many smartphone users! The only bad thing I can see about the RR-1 for blind users is that "Light" button next to the "Start" button that could turn the light on even if the oven is off... Now how could they tell if the light is on or off once the door is closed!? It must be just as annoying to them as those Tap-Lite switches or 3 way light switches I guess!
Back on the subject!
I'm wondering what would the infrared camera see if the outside of food was getting evenly hot but the inside still frozen?
My Hitachi microwave oven from the early-eighties has an automatic sensor with 3 settings. I can tell you it doesn't work that well... I don't know if it measures heat, moisture or both but if you just want to re-heat something that has been refrigerated, it will stop too soon even on the "high" setting. Unless you want to soften ice cream like I often do, then it might stop too late!
And of course, there are those meat and candy temperature probes which were popular in many mid-1970s / 1980s models, these really measured the internal food temperature! Anyone wants a microwave roast beef?!
LOL!
Here's an old UK ad for the Hitachi

We had a full size GE back in the late 80's with auto cook, auto roast, auto defrost and probe and that thing was darned near perfect. It only crapped about about 4 years ago. I'd grab another if'n when one shows up.
My GE "Spacemaker" JVM150...
....from 1988 has the "Auto Cook", "Auto Defrost" and "Auto Roast" features and is usually "spot on" when it comes to the "Auto Cook" function. I use it for frozen vegetables and heating up left-overs. The oven uses "moisture sensing" to determine when the cooking is completed and it seems to work just fine in most cases. I rarely use the temperature probe but when I do, it works just fine as well. This oven has been VERY reliable with only ONE repair in the 27 years it's been in service.

My 2008 Panasonic "inverter" microwave does a pretty good job.
It has options for "Sensor Reheat" and "Sensor Cook" and both work fairly well. The reheat function makes a couple of beeps toward the end and the display begins a countdown, which varies in length depending on how long the contents took to reheat. I've found that when the beeps happen and the countdown starts, shut it down because it's already done.

Panasonic Inverter MW
Ralph,
Your Panasonic oven most certainly has a moisture/heat sensor in the cavity exhaust air duct. They use this as feed back for some of the automatic cycles. The couple Panasonic Inverter ovens I have repaired have both had this feature. The one I replaced the HV Inverter transistors was from about 2003 (and happily its still working a few years after my repair!).
The idea of a microwave sensing heat isn't entirely new...
