摘要： Example embodiments of a near-Infrared (NIR) sensor system and methods for detecting changes in polarization are generally described herein. Other example embodiments may be described and claimed. In some example embodiments, the sensor system includes a transmit optical element to transmit optical signals with a polarization, and a receive optical element to receive optical signals with an orthogonal polarization. The transmit and receive optical elements may include nano-imprinted wire-grid polarizers configured to polarize at least infrared IR wavelengths. In some example embodiments, birefringent filter layers may be used to induce an additional polarization state on the transmitted and received optical signals.
