a Schematic of the omnidirectional photoresponse measurement setup. A hemispherical PMMA light controller is aligned and placed on the photodetectors. b Si/Cr photodetectors at the spherical center of omnidirectional light controller. c Schematic of DNN-assisted analysis of the incident angle. d Relationship between responsivity and power of different photodetectors. e Current-Time relationship of different structures illuminated by 520 nm laser. XY plane projection of the photoresponse through the structure of f planar, g ring, h arch, i helix, j taper, and k tube photodetectors. l The epoch-dependent recognition accuracy of training set in longitudinal and latitudinal direction using DNN. m Angle identification of incident angle in longitudinal (φ = 0°) and latitudinal (θ = 40°) direction. n Weight mapping of output angles and input angles of longitudinal direction (φ = 0°). Source data are provided as a Source Data file.
