A microfluidic diffraction device is developed for determination of CTC/bacteria from human whole blood with a home-constructed laser beam system. We design the optical structuretransfer the structure to transparent plastic substrate. The plastic diffraction die is modified with antibodies of the target to combine a fluidic system as a microfluidic diffraction chip. When human whole blood with CTCs/bacteria flows through the chip, the number of cells/bacteria can be obtained directly with label-free. The devices has been applied in clinical diagnosis of oesophagealendometrial cancer.

We developed a Multiview 3D capturing system based on camera array for generating stereoscopic 3D printing. Based on the framework, we are capable to create well aligned 3D contentcalibrated color images. The depth perception of content can be manually adjusted for preview,for generating quality 3D stereoscopic printing.
