Zusammenfassung:	Techniques are disclosed for imager health monitoring systems and methods. In one example, a method includes determining a characteristic of an active unit cell of a focal plane array (FPA) and/or a reference unit cell of the FPA. The active unit cell includes a detector selectively shielded from an incident scene. The reference unit cell includes a reference detector shielded from the incident scene. The method further includes determining a state of the FPA based at least in part on the characteristic. The method further includes transmitting an indication of the state of the FPA to selectively cause adjustment of the FPA Related devices and systems are also provided.
