DiffuserCam: Lensless Single-exposure 3D Imaging
We demonstrate a compact and easy-to-build computational camera for single-shot 3D imaging. Our lensless system consists solely of a diffuser placed in front of a standard image sensor. Every point within the volumetric field-of-view projects a unique pseudorandom pattern of caustics on the sensor. By using a physical approximation and simple calibration scheme, we solve the large-scale inverse...
متن کاملSingle-frame 3D fluorescence microscopy with ultraminiature lensless FlatScope
Modern biology increasingly relies on fluorescence microscopy, which is driving demand for smaller, lighter, and cheaper microscopes. However, traditional microscope architectures suffer from a fundamental trade-off: As lenses become smaller, they must either collect less light or image a smaller field of view. To break this fundamental trade-off between device size and performance, we present ...
متن کاملSingle-molecule Enzyme Assay with a Lensless Flouorestcent Imaging Device
In this paper, we report on demonstration of digital counting of enzyme based on fluorescent femtoliter droplet array imaging by using a lensless CMOS image sensor. The result supports the device can be applied to digital enzyme linked immunosorbent assay (ELISA). Digital ELISA is an ultra-sensitive detection technique for a biomarker [1, 2]. In the previous work, we developed a miniature lensl...
متن کاملLensless Compressive Imaging
We develop a lensless compressive imaging architecture, which consists of an aperture assembly and a single sensor, without using any lens. An anytime algorithm is proposed to reconstruct images from the compressive measurements; the algorithm produces a sequence of solutions that monotonically converge to the true signal (thus, anytime). The algorithm is developed based on the sparsity of loca...
متن کاملLensless Imaging and Sensing.
High-resolution optical microscopy has traditionally relied on high-magnification and high-numerical aperture objective lenses. In contrast, lensless microscopy can provide high-resolution images without the use of any focusing lenses, offering the advantages of a large field of view, high resolution, cost-effectiveness, portability, and depth-resolved three-dimensional (3D) imaging. Here we re...
