*** 9760845 Aye This Small Business Innovation Research (SBIR) Phase I project will develop a Micro-Optic Spectroscopic Imaging Sensor (MOSIS), based on a polarization sensitive diffractive micro-optic array. MOSIS will be a miniature, compact, lightweight monolithic device capable of multi-spectral, polarimetric imaging in real time. Phase I will microminiaturize a conventional spectrographic system using a refractive-diffractive micro-optic array, integrated with a high resolution charge-coupled-device (CCD) array to form a two-dimensional (2-D) imaging sensor. Because of the focusing property of the refractive element and the high spectral dispersion of the diffractive elements, the device will perform high resolution (1-10 nanommeters) spectroscopic image detection in a broad visible-to-mid IR spectral range. This MOSIS is a simple monolithic focal-plane array consisting of a stack of three basic elements: (1) a refractive microlens array; (2) a pair of conjugate birefringent diffractive optics arrays; and (3) a 2-D detector array, which can be a commercial CCD chip. This approach can be applied to any desired bands of the optical spectrum without any limitations imposed by materials or fabrication processes as in the passive (holographic or multilayer) and active (acousto-optic or liquid crystal) filter-based devices. Applications are expected in compact, low-cost, reliable, polarimetric imaging, multispectral sensor systems for remote sensing in ocean monitoring, environmental sensing, mineral identification, agricultural surveillance, biomedical and chemical spectroscopic imaging, and industrial inspection. ***

*** 小行星9760845 该小型企业创新研究（SBIR）第一阶段项目将开发基于偏振敏感衍射微光学阵列的微光分光成像传感器（MOSIS）。 MOSIS将是一种微型、紧凑、轻便的单片设备，能够进行真实的多光谱偏振成像。 第一阶段将使用折射衍射微光学阵列对传统的光谱系统进行微处理，该阵列与高分辨率电荷耦合器件（CCD）阵列集成，以形成二维（2-D）成像传感器。 由于折射元件的聚焦特性和衍射元件的高光谱色散，该设备将在宽的可见光到中红外光谱范围内执行高分辨率（1-10纳米）光谱图像检测。 该MOSIS是一种简单的单片焦平面阵列，由三个基本元件的堆叠组成：（1）折射微透镜阵列;（2）一对共轭双折射衍射光学阵列;和（3）2-D检测器阵列，其可以是商业CCD芯片。 这种方法可以应用于光谱的任何期望的波段，而没有如在基于无源（全息或多层）和有源（声光或液晶）滤波器的设备中那样由材料或制造工艺施加的任何限制。 预计将应用于小型、低成本、可靠的偏振成像、多光谱传感器系统，用于海洋监测、环境传感、矿物鉴定、农业监测、生物医学和化学光谱成像以及工业检查中的遥感。 ***
