Abstract
A light-modulated photodiode-based monitor for detecting a control signal of a display is disclosed. The monitor includes an emitter configured to emit a control signal, a polarizer configured to linearly polarize the pulsed signal, one or more fold mirrors configured to reflect the pulsed signal from the emitter onto a test portion and/or reflect the pulsed signal that has reflected off of the test portion. The monitor further includes an analyzer configured to block or transmit the polarized pulse signal reflected from at least one of the fold mirror or the test portion, and a detector configured to receive the pulsed signal transmitted from the analyzer and convert the pulsed signal into an electrical signal. The monitor further includes a controller that includes one or more processors and is configured to receive the electrical signal, filter and rectify the electrical signal, and determine a functional state of the display.
