Freeform super-oscillatory optics for CMOS-integrated THz super-resolution imaging
Jin Chen, Liang Gao, Hao Guo +5
The diffraction limit fundamentally constrains the spatial resolution of far-field imaging systems. While near-field techniques can circumvent this limit, their inherently short wo…

An integrated super resolution THz 3D imaging system based on a linear nonlocal achromatic freeform Bessel beam lens and high power oscillator radiator array
Jin Chen, Liang Gao, Hao Guo +5
High performance terahertz (THz) 3D imaging is critical for non-destructive evaluation. However, conventional architectures are fundamentally limited by severe chromatic aberration…
