A review is given of the properties of birefringently phase-matched parametric upconversion using proustite as the nonlinear material. Photon conversion efficiency, field-of-view limitations, spectral acceptance bandwidths, and resolution are discussed in terms of the upconversion of radiation from the 10-mu region to wavelengths shorter than 1 mu. The competitive potential of upconversion detection systems is examined for a wide variety of sensor applications. This analysis shows that upconversion represents a special-purpose detection technology appropriate for low-duty-cycle, small field-of-view imaging systems that use laser illumination. Competitive development of upconversion to detect thermal imagery appears unlikely.
本文综述了以硫溴银矿作为非线性材料的双折射相位匹配参量上转换特性。从10微米波段的辐射上转换到短于1微米的波长，讨论了光子转换效率、视场限制、光谱接收带宽和分辨率。针对各种传感器应用，研究了上转换检测系统的竞争潜力。该分析表明，上转换是一种适用于使用激光照明的低占空比、小视场成像系统的专用检测技术。上转换用于检测热成像的竞争性发展似乎不太可能。
