Abstract

Optical diffraction tomography (ODT) as a kind of label-free three-dimensional imaging technique has been widely used in biomedical imaging. To decrease the volume of ODT instrumentation and broaden the applications of the ODT technique, we propose a novel design to achieve a miniaturized ODT system based on using a vertical-cavity surface-emitting laser (VCSEL) array and a self-interference unit. In our proposed system design, a dome-shaped VCSEL array is used to generate angle scanning illuminations, and the self-interference unit is applied to record the off-axis interferograms from different illumination angles. We have verified the accuracy of phase retrieval of our system and investigated the proper illumination angles and reconstruction model for further system development.
