NEC Shrinks IR Pixel to Less Than Wavelength Size

Tech-On: NEC has developed an uncooled VGA IR sensor with pixel pitch of 12um. The sensor operates in 8-14um band, so its pixel size is less than one wavelength. The pixel is based on NEC's own MEMS technology.

    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...
