A theoretical design of a reconfigurable detector array assembly is presented. This device is capable of changing the angular resolution and thermal sensitivity of the electro- optics array in real time. The apparent layout (i.e., size, spacing, and location) of the focal plane array detector elements is dynamic. This approach allows varying the instantaneous field-of-view as a function of the field angle, and combining adjacent spectral bands when poor atmospheric conditions are presented. This infrared reconfigurable hyperspectral focal plane array (IR-RHFPA) provides a way to get rid of some of the problems related to multi-spectral imagery sensors such as data rate, bow-tie effect, and sensitivity. Curves of spatial resolution versus field angle, and thermal sensitivity versus wavelength are obtained for the proper design and optimization of the IR-RHFPA. The potential operational configurations that best satisfy the system requirements are identified and displayed.
