Abstract

We present the development of stereoscopic shadow microscopy, which is arguably the most simple 3D microscopy because it is lens-free and it only needs a pair of coloured shadow images. Two spectrally-modulated light sources illuminate the object and cast two sets of coloured shadow images directly on an array of digital pixel sensors. The magnified 3D image of the object can be stereoscopically visualized simply by using a digital screen and a pair of spectrally-modulated glasses. Our analytical model shows that the optimal position of the object is governed by both the positions and the dimensions of the light sources.
