Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors
Advanced Science, EarlyView.A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

Stereo Matching in the Presence of Sub-Pixel Calibration Errors [PDF]
, 2009 Stereo matching commonly requires rectified images that are computed from calibrated cameras. Since all under-lying parametric camera models are only approximations, calibration and rectification will never be perfect.
