Abstract
A sensing system may include a first coded aperture configured to receive incident light and transmit a coded image of an object. The sensing system comprises a light replication component configured to detect the coded image and emit a replicated coded image. The sensing system may include a second coded aperture configured to receive the replicated coded image and transmit a decoded image. The sensing system may include a sensor configured to detect the decoded image.
Claims12
A sensing system comprising:
- first coded aperture configured to receive incident light and transmit a coded image;
- a light replication component configured to detect the coded image and emit a replicated coded image;
- a second coded aperture configured to receive the replicated coded image and transmit a decoded image;
- a sensor configured to detect the decoded image,
- wherein the light replication component comprises:
- an incident light receiving surface and an opposed light emitting surface;
- a substantially transparent planar substrate;
- one or more bipolar junction transistors provided on the substantially transparent planar substrate, each transistor comprising a collector region adjacent to the light receiving surface, an emitter region adjacent to the light emitting surface, and a base region between the collector region and the emitter region;
- and
- circuitry for biasing the bipolar transistors in use,
- wherein each transistor is configured and biased in use so that the collector and base regions of the transistor operate as a photodiode while the base and emitter regions operate as a light emitting diode.
