1. A method comprising:
repeatedly closing a set of one or more shutters of a set of one or more corresponding image sensors of a system, each image sensor of the set of one or more image sensors having a plurality of pixels;
while the set of one or more shutters are closed, detecting one or more photodetectors among the plurality of pixels of at least one image sensor of the set of one or more image sensors that are excited beyond a predetermined excitation threshold;
determining a soft error rate for the system based on detecting that one or more photodetectors among the plurality of pixels of at least one image sensor are excited beyond the predetermined excitation threshold; and
implementing one or more system countermeasures to compensate for the soft error rate.
