A single-shot quadrature phase-shifting interferometry architecture is presented that is applicable to antenna coupled detector technologies. The method is based on orthogonally polarized object and reference beams and on linear and circular polarization sensitive antennas in space-division multiplexing. The technique can be adapted to two-, three-, and four-step and Gabor holography recordings. It is also demonstrated that the space-division multiplexing does not necessarily cause sparse sampling. A sub-THz detector array is presented containing multiple on-chip antennas and FET plasma wave detectors implemented in a 90 nm complementary metal-oxide semiconductor technology. As an example, two-step phase-shifting reconstruction results are given at 360 GHz.
提出了一种适用于天线耦合探测器技术的单拍正交相移干涉测量架构。该方法基于正交偏振的物光束和参考光束，以及在空间复用中的线极化和圆极化敏感天线。该技术可适用于两步、三步和四步以及 Gabor 全息记录。还证明了空间复用不一定会导致稀疏采样。本文提出了一个亚太赫兹探测器阵列，其中包含多个片上天线和在 90nm 互补金属氧化物半导体技术中实现的 FET 等离子体波探测器。作为一个例子，给出了在 360GHz 时的两步相移重建结果。
