MEMS based multispectral confocal probe

A MEMS based handheld multi-spectral confocal microscope has been developed as a noninvasive imaging instrument for cervical cancer screening. Tissue imaging depth of up to 400 μm was demonstrated. The maximum speed of image collection is up to 10 Hz with field of view (FOV) around 200×158 pixel

size. Our handheld prototype is able to visualize cancer cells with cellular resolution (transverse resolution = 5 μm and axial resolution = 6 μm). Biological imaging demonstration was carried out on cell culture and tissues of human cervix.
