new thermomechanical terahertz detector

Simpler than that. Drive them all CW and look at the response phase by using the multiplexer as a sample/hold phase detector.

Yup. Probably not going to be cheaper than a microbolometer though.

Farnsworth's original camera tube was the Image Dissector, which scanned the entire electron image across the aperature of a small photomultiplier. So for N pixels, he wasted (N-1)/N of the available photoelectrons. Actors don't enjoy performing under arc lights.

Same idea, scan and throw away most of the signal.

The MEMS resonators can, however, continue to accumulate phase error whether you are looking at them or not. That's more like a vidicon, where the pixels keep accumulating signal between readout hits.

Yes, as long as you sample them faster than f0/Q.
