项目摘要

The potential benefits of passive millimeter-wave imaging have long been recognized. It is an enabling technology for imaging and detection in degraded visual environments. The large range of applications for this technology include astronomy, aerial reconnaissance, stand-off threat detection, portal screening, persistent surveillance, situational awareness, and video imaging navigation in the absence of GPS signals. Millimeter-wave imaging can provide for high resolution and has the added capability to "see through" smoke, fog, sandstorms, and clouds. Therefore, it can provide pilots with valuable situational awareness during hover, takeoff and landing operations. Further, millimeter-wave radiation penetrates through plastic and clothing. With these advantages in mind, a Passive Millimeter-Wave Imaging camera system can be used as a complementary sensing modality in the emerging field of multi-sensor data fusion, and in conjunction with visible spectrum and infra-red (IR) cameras, LADAR (Laser Radar, a.k.a. LIDAR), RFID, and other range sensors to achieve inferences not possible with a single sensing modality. To date, most fielded millimeter-wave imaging systems focus on body scanning, as encountered at airports and building entrances. These systems are considered effective, but not without drawbacks. Specifically, they are bulky, slow, expensive, conspicuous and not suitable for standoff imaging. Therefore, there is a need for low-cost, compact, sensitive, and versatile imaging systems to enable a broader field of imaging applications. Medical and other scientific fields can also benefit from a small and high-performance millimeter-wave imaging camera. The proposed research introduces a new millimeter-wave camera design with integrated antennas and a photonic chip front-end using optical up-conversion, all in a staring interferometric sparse array format for high contrast and high spatial resolution. In the proposed camera system, the incident millimeter-wave radiation modulates an optical signal within an optical electro-modulator. The modulated signal, which consists of the optical carrier and double sidebands, is then stripped of the carrier and one of the sidebands using an integrated on-chip optical bandpass filter before being projected onto a standard near-IR camera. A number of innovative approaches are proposed to achieve small camera footprint, sensitivity, low cost and better resolution: 1) front-end antenna array with integrated optical up-conversion for black-body radiation centered at 94 GHz without a need for amplification, 2) increased efficiency by directly integrating the millimeter-wave antenna onto the electro-optical modulator and the optical bandpass filter on a single chip, 3) electro-optical modulator architecture using the electro-optic effect in polymer material in the active area for low loss and high modulation efficiency, 4) engineered sol-gel properties that promote high polling efficiency, low optical propagation losses, and efficient single mode fiber coupling, 5) standard optical lens and near-IR commercial cameras for low cost and simple reconstruction of high resolution images, and 6) interferometric sparse staring array detector front-end architecture for video rate functionality that avoids RF refractive lens in the front-end. The impact of this research is profound at many levels. The proposed camera will have a transformational impact since it can be used in the same manner as an optical camera to identify and detect hidden objects below clothing or behind obscurants at high speed. The proposed millimeter-wave camera is of low cost, real time, high resolution and high contrast. Notably, the modulator developed for this camera will benefit a multitude of portable devices for other research fields and many applications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
被动毫米波成像的潜在好处早已被认识到。它是在退化的视觉环境中成像和检测的一种使能技术。该技术的广泛应用包括天文学、空中侦察、远距离威胁探测、门户筛选、持续监视、态势感知以及在没有GPS信号的情况下的视频成像导航。毫米波成像可以提供高分辨率,并具有“看穿”烟雾、雾、沙尘暴和云的附加能力。因此,它可以在悬停、起飞和着陆操作期间为飞行员提供有价值的态势感知。 此外,毫米波辐射可以穿透塑料和衣服。考虑到这些优点,无源毫米波成像相机系统可以用作多传感器数据融合的新兴领域中的补充感测模态,并且与可见光谱和红外(IR)相机、LADAR(激光雷达,又称LIDAR)、RFID和其他范围传感器,以实现利用单一感测模态不可能实现的推断。到目前为止,大多数现场毫米波成像系统专注于身体扫描,如在机场和建筑物入口处遇到的。这些系统被认为是有效的,但并非没有缺点。具体地说,它们体积大、速度慢、昂贵、显眼,并且不适合远距离成像。因此,需要低成本、紧凑、灵敏和通用的成像系统,以实现更广泛的成像应用领域。医疗和其他科学领域也可以从小型高性能毫米波成像相机中受益。 拟议的研究介绍了一种新的毫米波相机设计与集成天线和光子芯片前端使用光学上变频,所有在凝视干涉稀疏阵列格式的高对比度和高空间分辨率。在所提出的相机系统中,入射的毫米波辐射调制光电调制器内的光信号。调制信号由光载波和双边带组成,然后使用集成的片上光学带通滤波器剥离载波和其中一个边带,然后投影到标准的近红外相机上。提出了许多创新的方法来实现小的相机足迹,灵敏度,低成本和更好的分辨率:1)前端天线阵列,其具有用于中心在94 GHz的黑体辐射的集成光学上变频,而不需要放大,2)通过将毫米波天线直接集成到单个芯片上的电光调制器和光学带通滤波器上来提高效率,3)在有源区中使用聚合物材料中的电光效应以实现低损耗和高调制效率的电光调制器结构,4)促进高轮询效率、低光传播损耗和有效单模光纤耦合的工程化溶胶-凝胶性质,5)用于低成本和高分辨率图像的简单重构的标准光学透镜和近IR商用相机,以及6)用于视频速率功能的干涉式稀疏凝视阵列检测器前端架构,其避免了前端中的RF折射透镜。这项研究的影响在许多层面上都是深远的。所提出的相机将具有变革性的影响,因为它可以以与光学相机相同的方式使用,以高速识别和检测隐藏在衣服下面或遮蔽物后面的物体。该毫米波相机具有低成本、真实的实时性、高分辨率和高对比度等优点。值得注意的是,为这款相机开发的调制器将使其他研究领域和许多应用领域的众多便携式设备受益。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
