论文摘要
许多光学显微镜技术通过投影图像(例如结构化照明显微镜)或光的角度分布(例如Ptychography)依赖于结构化照明。电流设备(例如空间光调节器和发射二极管(LED)阵列)通常用于雕刻这些成像方案的光。但是,这些高科技设备并不是轻型制作的要求。图案化的扩散反射表面也将空间角结构贴在反射的光线上。我们证明,用标准商用打印机图案图案的纸可以用于在手机显微镜上重新关注和立体声显微镜的照明光场。我们的结果说明了纸作为低技术计算成像的光雕刻元素的实用性。
Many optical microscopy techniques rely on structured illumination by way of a projected image (eg. structured illumination microscopy) or a tailored angular distribution of light (eg. ptychography). Electro-optical equipment such as spatial light modulators and light emitting diode (LED) arrays are commonly used to sculpt light for these imaging schemes. However, these high-tech devices are not a requirement for light crafting. Patterned diffusely reflecting surfaces also imprint a spatio-angular structure onto reflected light. We demonstrate that paper patterned with a standard commercial printer can serve to structure the illumination light field for refocusing and stereo microscopy on a mobile phone microscope. Our results illustrate the utility of paper as a light sculpting element for low-tech computational imaging.
