QMHP: Multichannel interscale mixing: towards highly-parallel subwavelength imaging and focusing of lightAbstractThe objective of research is to develop a novel imaging paradigm that eliminates the need for bulky optical components such as lenses or mirrors and provides dramatic improvement of resolution. The approach relies on carefully designed diffractive elements that enable coupling between the waves carrying the information about different lengthscales of the object, and on advanced computational algorithms that recover the image based on the set of measured diffraction patterns. Intellectual merit: Proposed research focuses on the development of fundamentally new approach to imaging that utilizes diffractive, rather than reflective or refractive optics. The research has full potential to combine the benefits of deep subwavelenght resolution, offered by scanning near-field optical microscopy with benefits of large-area imaging offered by structured illumination microscopy. Diffraction-assisted imaging is uniquely positioned to utilize the four-fold reduction in wavelength in typical semiconductors to reduce the pixel size in mid-IR and long-wave IR detectors by an order of magnitude, opening the road to build highly-compact optics in these important frequency ranges.Broader ImpactsProposed research presents an opportunity to use recent progress in computation, materials science, and fabrication to revolutionize the full spectrum of imaging systems, from table-top microscopes to portable cameras, affecting life of ordinary people and researchers alike. The developed paradigm may become the ?workhorse? for optical characterization of novel nanostructures and for in-situ real-time imaging of small biological systems. Proposed mentoring, teaching, and outreach programs address the needs of high-school, undergraduate, and graduate students, and take advantage of the established productive theory-experiment collaborations

QMHP：多通道尺度混合：实现高度并行的亚波长成像和光聚焦摘要研究的目的是开发一种新颖的成像范例，消除对笨重光学组件（例如透镜或镜子）的需求，并显着提高分辨率。该方法依赖于精心设计的衍射元件，这些元件能够在携带物体不同长度尺度信息的波之间进行耦合，并且依赖于先进的计算算法，该算法可以根据测量的衍射图案集恢复图像。智力价值：拟议的研究重点是开发利用衍射光学而不是反射或折射光学的全新成像方法。该研究完全有潜力将扫描近场光学显微镜提供的深亚波长分辨率的优点与结构照明显微镜提供的大面积成像的优点结合起来。衍射辅助成像具有独特的优势，可以利用典型半导体的波长缩短四倍，将中红外和长波红外探测器的像素尺寸减小一个数量级，从而为在中红外和长波红外探测器中构建高度紧凑的光学器件开辟道路。这些重要的频率范围。更广泛的影响拟议的研究提供了一个机会，利用计算、材料科学和制造方面的最新进展来彻底改变从台式显微镜到便携式相机的整个成像系统，影响普通人和研究人员的生活一样。开发出来的范式可能会成为“主力”。用于新型纳米结构的光学表征和小型生物系统的原位实时成像。拟议的指导、教学和推广计划满足高中生、本科生和研究生的需求，并利用已建立的富有成效的理论实验合作
