1. An optical device comprising:
a semiconductor chip having a first surface that receives incident light, which passes through transparent regions of the optical device,
a plurality of electro-optical circuits formed on the semiconductor chip, the plurality of electro-optical circuits including:
light emitters configured to output display light, and the transparent regions being arranged among the light emitters; and
detectors, each detector of the detectors being associated with one or more light emitters of the light emitters, and the detectors being configured to detect respective signals representing an intensity of the incident light, wherein
an intensity of the display light output by the one or more light emitters depends on the signal detected by the associated detector, and wherein the intensity of the display light output by the one or more light emitters augments the incident light to amplify or correct the incident light, based on the signal detected by the associated detector.
