Abstract
We present a field-portable lensfree tomographic microscope, which can achieve sectional imaging of a large volume (∼20 mm3) on a chip with an axial resolution of Hymenolepis nanaegg, which is an infectious parasitic flatworm. Achieving a decent three-dimensional spatial resolution, this field-portable on-chip optical tomographic microscope might provide a useful toolset for telemedicine and high-throughput imaging applications in resource-poor settings.
