Lensfree On-chip Tomographic Microscopy Employing Multi-angle Illumination and Pixel Super-resolution

11.9K
Lensfree optical tomography is a three-dimensional microscopy technique that offers a spatial resolution of <1 μm × <1 μm × <3 μm in x, y and z dimensions, respectively, over a large imaging-volume of 15-100 mm3, which can be particularly useful for integration with lab-on-a-chip...
