提出了一种新的基于双数字成像器件的光学采集方案，并将其应用于混浊介质的三维层析成像。通过使用对照明检测模式与一个单一的检测器，我们能够进行高分辨率的定量体积成像的吸收异质性嵌入在光学厚的样品。此外，在图形处理器单元上实现断层重建算法，以2 Hz的帧速率提供光学重建。在这项工作中提出的结构化照明方法具有显着的成本优势，相机系统，因为只需要一个单一的检测器。这种配置还具有提高帧速率的潜力。(C)2010年，美国光学仪器工程师学会（Society of Photo-Optical Instrumentation Engineers）[DOI 10.1117/1.3290818]
A new optical acquisition scheme based on a pair of digital micromirror devices is developed and applied to three-dimensional tomographic imaging of turbid media. By using pairs of illumination-detection patterns with a single detector, we were able to perform high-resolution quantitative volumetric imaging of absorption heterogeneities embedded in optically thick samples. Additionally, a tomographic reconstruction algorithm was implemented on a graphical processor unit to provide optical reconstructions at a frame rate of 2 Hz. The structured illumination method proposed in this work has significant cost advantages over camera systems, as only a single detector is required. This configuration also has the potential to increase frame rate. (C) 2010 Society of Photo-Optical Instrumentation Engineers. [DOI: 10.1117/1.3290818]
