Transcending the Space‐Bandwidth and Lighting Trade‐Offs: A Programmable Self‐Mixing Interferometry Imager for Cross‐Scale Surface Inspection

ABSTRACT Industrial optical inspection is fundamentally limited by the trade‐off between spatial bandwidth (field‐of‐view vs. resolution) and vulnerability to ambient lighting. This work addresses these challenges by proposing a programmable imager based on amplitude‐modulated la...
