Figure 1. Scene points to sensor pixels mapping in different imaging modalities.

(a) Coherent fiber bundle or an image guide coherently maps the scene (the letter “A”) onto the sensor. (b) Incoherent fiber bundle shuffles the pixels and feeds them to the sensor. (c) Optical brush randomly samples and shuffles the scene and then sends it to the sensor. (d) A hypothetical swarm optical sensor network can collectively image inside a medium, the pixels are communicating with each other.
