High resolution microscopy using a scattering layer

具有良好成像质量和高分辨率的显微镜物镜价格昂贵且体积庞大。同时，固定的焦距、工作距离、有限的焦距和放大倍率限制了其适用性。像差是经典显微镜物镜的另一个挑战。因此，有一个日益增长的需要紧凑型光学显微镜成像系统具有可调的焦距，高分辨率和无像差。该项目的目标是开发一种对微观样品成像的技术，而不是像传统显微镜那样使用显微镜物镜，而是使用散射表面。物体的图像将通过处理由漫射器衍射的光来检索，并记录在像素化传感器上。新开发的显微镜将提供亚微米分辨率和无像差图像。此外，它同样适用于较短的（紫外线，x射线）和较长的（红外）波长。所开发的技术将用于生物成像和技术样本的调查。

Microscope objectives having good imaging quality and high resolution are expensive and bulky. At the same time, fixed focal length, working distance, limited depth of focus and magnification restrict their applicability. Aberrations are an additional challenge of classical microscope objectives. Consequently, there is a growing need for compact optical microscopy imaging systems with adjustable depth of focus, high resolution and free of aberration. The goal of the project is the development of a technique for imaging microscopic samples, where instead of a microscope objective, like in conventional microscopy, a scattering surface is applied. The image of the object will be retrieved by processing the light diffracted by the diffuser, recorded on a pixelated sensor. The newly developed microscope will deliver submicrometer resolution and aberration free images. Furthermore, it will likewise be applicable to shorter (UV, X-rays) and longer (infrared) wavelengths. The developed technique will be used for biological imaging and investigation of technical samples.
