摘要
阐述了光电混频技术的基本原理。基于独立光电器件和组合光电器件两种实现途径,追踪并归纳了光电混频技术的研究进展。受微波光子变频技术的启发,提出了一种基于体型电光调制器的光电混频方法。该方法使用电光调制器在光场进行混频解调,后端采用高分辨率、低成本的图像传感器,突破了阵列尺寸对图像分辨率的限制,具有高能量利用率、高信噪比的优势。
Abstract
The basic principle of the photoelectric mixing technology is elaborated. The research progress of the photoelectric mixing technology is traced and summarized from two ways of the independent photoelectric devices and the combined photoelectric devices. Inspired by the microwave photon frequency conversion technology, a photoelectric mixing method is proposed based on the bulk electro-optic modulator. This method uses the electro-optic modulator to demodulate the frequency mixing on the optical field and uses the high-resolution and low-cost image sensors at the back end, which breaks through the limitation of the array size on the image resolution and achieves the advantages of high energy efficiency and high signal-to-noise ratio.
