Is this PN junction based? What is the NETD?
NEC makes microbolometric imagers since 2007 or so. This new one is said to use MEMS processing, so, I'd guess, it's bolometric too.
The cool thing about this sensor is that it is uncooled.NETD = Noise Equivalent Temperature Difference (a temperature difference resulting in a signal being equal to noise).
I understand the meaning of NETD, of course :). My question was on the value of NETD. haha...
