Abstract
A system is disclosed that display configured to transmit a signal that includes a first light configured as a display image and a second light configured as a reference image. The system also includes a beam splitter, a selectively transmissive mirror and a sensor configured to detect the second light. The beam splitter is configured to receive the signal from the display and reflect the signal to the selectively transmissive mirror. The selectively transmissive mirror is configured to receive the reflected signal, transmit the second light toward a sensor, and reflect the first light, wherein the first light is configured with a first bandwidth, wherein the second light is configured with a second bandwidth. The system further includes a corrector lens configured to receive the first light and transmit the first light to an exit pupil.
