Oh, that's right the Low Cost Thermal Imager already has a name, PIXNET

now a prototype. And it's multispectral.

"A prototype sensor technology under development will enable soldiers to identify threats more rapidly in low-light environments and to share target images with other squad members. Consisting of several types of small multispectral cameras, the system will use smartphone technology in the form of a warfighter’s handheld mobile device to process and fuse the camera data into high-resolution color images for the soldier’s helmet display. That display imagery can then be transmitted wirelessly to other soldiers."
