Abstract
Techniques are disclosed for optical imager devices, systems, and methods. In one example, an imaging system includes a focal plane array (FPA) and a light shield. The FPA includes a detector array configured to detect a first portion of electromagnetic radiation and generate a detector signal based on the first portion. The FPA further includes a readout circuit coupled to the detector array and configured to receive the detector signal. The light shield is coupled to the FPA and configured to block a second portion of the electromagnetic radiation. Related devices and methods are also provided.
