Abstract
The emitting area of the infrared sources comprising silicon micromachined thermal pixel arrays is often notably smaller than the actual pixel area. This results in the infrared sources being operated at higher temperatures than apparent temperatures which therefore limits radiometric dynamic range. An optomechanical means has been developed that transforms the low-fill factor devices into having a much higher fill factor. The theory, fabrication, and initial tests results are presented.
