Code from: Self-reconfigurable polarization perception in dual-anisotropy heterostructures enables high-dimensional in-sensor computing

Polarization encodes vectorial optical information invisible to
conventional intensity-only sensors but critical for advanced artificial
vision. Implementing in-sensor computing along the polarization dimension,
however, remains challenging due to the lack of reconfigurable array-level
hardware. Here, we demonstrate self-reconfigurable polarization sensor
arrays built from epitaxial van der Waals heterostructures of 2D tellurium
and ReS₂ with orthogonal in-plane anisotropies. Light-driven interfacial
carrier transfer and trapping synergistically produce a bipolar
photoresponse, while perpendicular lattice alignment yields opposite
polarization sensitivities in the two response branches, enabling
all-optical reconfiguration without electrical bias. Integrated into
in-sensor architectures, these arrays process time-resolved,
multi-dimensional optical information with high fidelity. Dynamic vision
tasks achieve enhanced accuracy (>95%), demonstrated in
applications ranging from autonomous driving to intelligent medicine. Our
results establish self-reconfigurable polarization arrays as a versatile
platform for high-dimensional in-sensor photonic computing, offering a
path toward efficient artificial vision in complex real-world
environments.
