    Heat-assisted detection and ranging is experimentally shown to see texture and depth through darkness as if it were day, and also perceives decluttered physical attributes beyond RGB or thermal vision.

    To integrate microchips with optical communications a photodetector is required to mediate the optical and electronic signals. Although germanium photodetectors are compatible with silicon their performance is impaired by poor intrinsic noise. Here the noise is reduced by nanometre engineering of optical and electrical fields to produce a compact and efficient photodetector.
