Abstract
An infrared detection system having a detector which includes elements of different sizes which are electrically selectable to change the operational range of the system without any change in the associated optical assembly. The detector elements can be of two or more element sizes, and various detector configurations can be employed such as single or dual detector configurations. To provide a constant signal amplitude for the different selected ranges, the gain of the detector circuitry can be adjusted accordingly to provide uniform signal amplitude irrespective of range setting.
