Abstract:
1. A method comprising: receiving a Focal Plane Array (“FPA”) having an identified defective region, the defective region corresponding to at least one defective pixel, the defective region being less than an entirety of the FPA, wherein the FPA comprises a Read-Out Integrated Circuit (“ROIC”) layer hybridized with a sensor layer; reading values from the ROIC layer under a dark condition; and irradiating a portion of the FPA based upon the values read from the ROIC layer under the dark condition by irradiating the defective region to anneal the at least one defective region without annealing a non-defective region of the FPA, wherein irradiating the defective region comprises applying at least one of a laser beam or focused acoustical energy to the identified defective region.
