PRECISE ANNEALING OF FOCAL PLANE ARRAYS FOR OPTICAL DETECTION

摘要

Precise annealing of identified defective regions of a Focal Plane Array (“FPA”) (e.g., exclusive of non-defective regions of the FPA) facilitates removal of defects from an FPA that has been hybridized and/or packaged with readout electronics. Radiation is optionally applied under operating conditions, such as under cryogenic temperatures, such that performance of an FPA can be evaluated before, during, and after annealing without requiring thermal cycling.

主权项

1. A system comprising:
a device configured to mount and position a Focal Plane Array (“FPA”) that comprises 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; and an emitter that irradiates the defective region of the FPA to anneal the defective region without annealing a non-defective region of the FPA.
