Abstract

Sensors that are capable of three-dimensional detection of depth field information in the spatial domain are of potential use in applications such as robotics, satellite imaging and medical assistance. However, current techniques require a precise light source for complex phase detection and diffraction, or involve static multidirectional reflection imaging. Here we report a reconfigurable heterostructure transistor array for monocular three-dimensional parallax reconstruction. The phototransistors are based on heterostructures of indium gallium zinc oxide and tungsten diselenide, and can operate as n-type, p-type or ambipolar transistors depending on electrostatic modulation. The arrays can be switched between two modes: a real-time constant perception mode for static imaging and a spatiotemporal planar configuration mode with memory for dynamic imaging. To switch between the modes, the dominant carrier polarity is changed via a complementary metal–oxide–semiconductor-compatible multiterminal addressing architecture. We show that the system can be used for three-dimensional morphology reconstruction, two-dimensional depth field mapping and multi-view coupling. Heterostructures of indium gallium zinc oxide and tungsten diselenide can be used to create phototransistor arrays capable of three-dimensional morphology reconstruction, two-dimensional depth field mapping and multi-view coupling.

用于单眼三维视差重建的可重构异质结构晶体管阵列

能够在空间域中三维探测深场信息的传感器在机器人、卫星成像和医疗援助等应用中具有潜在的用途。然而，目前的技术需要精确的光源来进行复杂的相位检测和衍射，或者涉及静态多向反射成像。本文报道了一种用于单眼三维视差重建的可重构异质结构晶体管阵列。该光电晶体管基于氧化铟镓锌和二硒化钨的异质结构，通过静电调制可以工作为n型、p型或双极晶体管。该阵列可以在两种模式之间切换：用于静态成像的实时恒定感知模式和用于动态成像的具有记忆的时空平面配置模式。为了在模式之间切换，通过互补的金属氧化物-半导体兼容多终端寻址体系结构改变主导载波极性。研究表明，该系统可用于三维形态重建、二维深度场映射和多视图耦合。
