Claim 32:
33. The method of claim 20, wherein the at least one optical device is a first optical device and a second optical device, the at least one optical transducer is a first optical transducer and a second optical transducer, the at least one electronic device is a first read-out-integrated-circuit (ROIC) and a second ROIC,
wherein the first optical device is configured to receive the optical signal,
wherein the first optical transducer is configured to receive the optical signal from the first optical device and convert the optical signal to a first electrical signal,
wherein the first ROIC is configured to receive the first electrical signal and process the first electrical signal,
wherein the second optical device is configured to receive the optical signal,
wherein the second optical transducer is configured to receive the optical signal from the second optical device and convert the optical signal to a second electrical signal,
wherein the second ROIC is configured to receive the second electrical signal and process the second electrical signal,, and further comprising:
a diagnostic fault detector configured to receive the processed first electrical signal and the processed second electrical signal, determines if an error occurred in either of the processed first electrical signal and the processed second electrical signal, and outputs a control signal; and
a switch configured to receive the processed first electrical signal, the processed second electrical signal, and the control signal, output the processed first electrical signal if no error occurred, and output a function of the first processed electrical signal and the processed second electrical signal that is error free when an error occurred.
