Lensfree On-chip Tomographic Microscopy Employing Multi-angle Illumination and Pixel Super-resolution
Published on: August 16, 2012
Abstract:
The computed tomography (CT) technique is implemented in an optical transmission microscope with a laser as a light source. A rotational Pechan prism is used in the illumination optics of the microscope for projecting a thick 3-D sample onto a 2-D array detector in different directions. A minicomputer is employed for 3-D reconstruction from the observed image data. Energy throughput efficiency and signal-to-noise ratio in the developed CT microscope are higher than those of our previously developed CT microscope [J. Opt. Soc. Am. A 4, 292 (1987)]. Instrumentation of this microscope is described and some experimental results are shown with biological samples.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
