This Small Business Innovative Research Phase I project will develop and deliver an indium gallium arsenide (InGaAs) active pixel focal plane array (FPA) capable of phase sensitive detection. The FPA will be sensitive to the short-wave infrared (0.9 `m to 1.7 `m) making it suitable for use with eye safe lasers. Each pixel of the FPA will act as a lock-in amplifier allowing the imager to detect low power modulated signals in the presence of high background illumination. This functionality will be useful in search and rescue operations by enabling detection and location of a low power signal beacon. In tracking applications it will dramatically reduce the power of the eye-safe laser required for operation in a sunlit background. Important commercial applications include near infrared spectroscopy. The phase sensitive imaging technology that will emerge from this program will represent a substantial advance and will be applicable to all spectral bands.

这个小型企业创新研究第一阶段项目将开发和提供一个砷化铟镓（InGaAs）有源像素焦平面阵列（FPA）相敏检测能力。FPA将对短波红外线（0.9 `m至1.7 `m）敏感，使其适合与人眼安全激光器一起使用。FPA的每个像素将作为一个锁定放大器，允许成像器在高背景照明的情况下检测低功率调制信号。 这一功能将有助于在搜索和救援行动中探测和定位低功率信号信标。在跟踪应用中，它将大大降低在阳光照射的背景下操作所需的人眼安全激光的功率。重要的商业应用包括近红外光谱。从该计划中产生的相敏成像技术将代表一个实质性的进步，并将适用于所有光谱波段。
