项目摘要
Optical spectroscopy and imaging allow remote, minimally-invasive monitoring of activities; provide morphological information that describes structure/shape; and may be used as a functional diagnostic tool for measuring of biochemical and physiological characteristics. Recent advances of photonics technology are the driving force behind many novel optical devices development. Various optical spectroscopy and imaging technologies have been investigated for applications in life sciences research (e.g. microscopic imaging), environmental sensing (e.g. water quality monitoring) and medical diagnosis (e.g. endoscopic imaging). **In practice, there are strong demands for miniaturized, integrated devices for in-situ applications. For example, in screening of cancers in the gastrointestinal (GI) tract, it is highly desired to have encapsulated, functional optical imaging modalities (fluorescence, Raman, etc.) for minimally-invasive detection of malignant lesions. Another example is implantable microfluidic and optical imaging based cellular analysis devices for continuously monitoring of the biochemical and physiological conditions of the patients as well as the environment. **Conventional optical spectroscopy and imaging systems are large, complex and costly optoelectronic instruments comprised of lasers, spectrophotometers, and detectors. Often, their size is the limiting factor for their use in certain applications such as in-situ monitoring of physiological processes and distributed environmental sensing. **Recent advances in micro-photonics and electronic devices have led to small but efficient components/modules such as diode lasers, single photon avalanche diodes detectors, microlenslets, and GRIN optics. When integrated with microfluidics technology, fully integrated devices can be made by Micro-electro-mechanical-systems (MEMS) or Micro-optical-electro-mechanical-systems (MOEMS). These technologies are mostly built upon well-established microelectronic technologies for integrated circuitry. When conventional devices are replaced with micro-components, new applications and capabilities can be facilitated. Moreover, it usually leads to significant cost reductions and increases in yield associated with mass production. **Although progresses have been made recently in the development of individual components such as micro-cantilevers, micro gratings, and micro-lens, etc, integration of these components into complete micro-spectroscopic and imaging devices remains as a very challenging problem. For a complete optical spectroscopic/imaging system, more complex components such as miniature light sources, photo detectors, and high-speed electronics are also required. Furthermore, medical and environmental application of these technologies raises new requirements such as toxicity, chemical/biological stability, and sterilization concerns. **The overall objectives of the proposed research program are to (i) develop integrated micro- optical spectroscopic technologies for spectrally- and temporally-resolved optical signal acquisition; (ii) investigate the integration of high speed photo detection modules into the micro-spectrometer; and (iii) development of a fully integrated encapsulated endoscope. The proposed program will be based on the Micro/Nano Systems Lab and focus on integrated device technology development. Its success will allow translation of such technology to applications in biomedical diagnosis, drug discovery, and environmental monitoring.
光谱学和成像允许远程、微创地监测活动;提供描述结构/形状的形态学信息;并且可以用作测量生化和生理特征的功能诊断工具。光子学技术的最新进展是许多新型光学器件发展的驱动力。各种光谱学和成像技术已经被研究用于生命科学研究(例如显微成像)、环境传感(例如水质监测)和医学诊断(例如内窥镜成像)中的应用。** 在实践中,对于现场应用的小型化集成器件有着强烈的需求。例如,在胃肠(GI)道中的癌症的筛查中,高度期望具有封装的功能性光学成像模态(荧光、拉曼等)。用于恶性病变的微创检测。另一个例子是可植入的基于微流体和光学成像的细胞分析装置,用于连续监测患者的生化和生理状况以及环境。** 传统的光学光谱和成像系统是由激光器、光电计和探测器组成的大型、复杂和昂贵的光电仪器。通常,它们的尺寸是它们在某些应用中使用的限制因素,例如生理过程的原位监测和分布式环境传感。** 微光子学和电子器件的最新进展导致了小型但高效的组件/模块,如二极管激光器,单光子雪崩二极管探测器,微透镜和GRIN光学器件。当与微流体技术集成时,完全集成的设备可以通过微机电系统(MEMS)或微光机电系统(MOEMS)制造。这些技术大多建立在用于集成电路的成熟的微电子技术上。 当传统器件被微型元件取代时,可以促进新的应用和能力。 此外,它通常导致与大规模生产相关的显著成本降低和产量增加。** 虽然最近在开发诸如微杠杆、微光栅和微透镜等单个组件方面取得了进展,但将这些组件集成到完整的显微光谱和成像设备中仍然是一个非常具有挑战性的问题。 对于完整的光学光谱/成像系统,还需要更复杂的组件,如微型光源,光电探测器和高速电子器件。此外,这些技术的医疗和环境应用提出了新的要求,如毒性、化学/生物稳定性和灭菌问题。** 拟议研究计划的总体目标是(i)开发用于光谱和时间分辨光信号采集的集成微光学光谱技术;(ii)研究将高速光检测模块集成到微型光谱仪中;以及(iii)开发完全集成的封装内窥镜。拟议的计划将以微/纳米系统实验室为基础,专注于集成器件技术的开发。它的成功将使这种技术转化为生物医学诊断,药物发现和环境监测的应用。
