Abstract

Based on the theory of frequency-shifted laser feedback and confocal technology

a laser feedback confocal tomographic system is designed. The light source in the system is a single longitudinal

linearly polarized Nd:YVO

microchip laser worked at the wavelength of 1 064 nm. It can magnify the frequency-shifted feedback signal by a factor of 106 and can realize optical tomography with a greater depth on the premise of high resolution. With the technology of scanning and image processing

the system can fulfill the three-direction imaging of a sample. The system has a lateral resolution of ~1 μm and a vertical resolution of ~15 μm. A two-dimensional imaging experiment for polyfoam and a foreign matter detection for inside onion are performed and the inner information images of the samples are obtained. The results show that the system designed has well tomographic ability and also good location ability for the foreign matter inside biological samples.
