摘要
A terahertz wave wide-beam imaging technology based on the block compressive sensing theory is proposed. Simulation results show that this technology can be used to achieve the rapid imaging with high resolution and high quality. With the CO2 gas laser light source of continuous terahertz wave and based on the wide-beam matrix modulation sampling, the different objects are imaged by block compressive sensing. The results are compared with that by the block compressive sensing method based on single-pixel random sampling. It is shown that the proposed technology has a higher imaging stability. Moreover, the sampling process is more universal for different imaging objects. © 2019, Chinese Lasers Press. All right reserved.
