SBIR Phase I: Spectral Imaging Micro-Mirror Array for Oceanographic Remote Sensing

这个小型企业创新研究第一阶段项目将展示，通过将电荷耦合器件(CCD)阵列与集成的体全息微镜阵列相结合，可以创建具有高空间、光谱和时间分辨率的光谱成像设备。在POC的光谱成像微镜阵列传感器(SIMMAS)设备中，微镜阵列将对成像到探测器阵列上的场景进行过滤，允许在简单的数字后处理后确定场景的光谱特征。由于滤光片阵列是无源的，系统的速度将仅受探测器和后处理系统的限制，这些系统将以视频帧速率运行。该设备的频带抑制特性将导致高信号吞吐量，产生高信噪比，并允许其使用低亮度。该项目的具体创新是创建了一个集成的全息微镜阵列，并将该阵列应用于光谱成像。SIMMAS设备可以广泛应用于紧凑和低成本光谱成像具有优势的商业场景。例如手持式现场检查系统、强大的工业检查系统。等离子发动机诊断系统(用于NASA应用)、医用生物传感器。和遥感(卫星)系统。

This Small Business Innovation Research Phase I project will demonstrate that a spectral imaging device with high spatial, spectral, and temporal resolution can be created by combining a charge-coupled device (CCD) array with an integrated array of volume holographic micro-mirrors. In POC's Spectral Imaging Micro-Mirror Array Sensor (SIMMAS) device, the micro-mirror array will filter the scene imaged onto the detector array, allowing the spectral characteristics of the scene to be determined after simple numerical post processing. Since the filter array is passive, the speed of the system will be limited only by the detector and post processing system, which will operate at video frame rates. The band-rejection nature of the device will result in high signal throughput, yielding a large signal-to-noise ratio and allowing its use low light levels. The specific innovations in the project are the creation of an integrated holographic micro-mirror array and the application of this array to spectral imaging. The SIMMAS device can be broadly applied to those commercial scenarios where compact and low-cost spectral imaging is advantageous. such as hand-held field inspection systems, robust industrial inspection systems. plasma engine diagnostic systems (for NASA applications), medical biosensors. and remote sensing (satellite) systems.
