Abstract

Some embodiments include a system having a detection sensor array, which includes multiple detection sensors with each detection sensor having an enabled state and a disabled state, and having a control module configured to operate the detection sensor array. Under the enabled state, each detection sensor is configured to detect and identify electromagnetic radiation, and under the disabled state, each detection sensor is configured not to detect and identify electromagnetic radiation. Further, the detection sensor array comprises a test state and an operational state. Other embodiments of related systems and methods are also disclosed.
