基于液晶显示器的无透镜单像素成像研究
Lensless single pixel imaging based on LCD
摘要
Abstract
Based on the single pixel imaging theory realized by acquisiting Fourier spectra,a single-pixel lensless imaging method is proposed by loading a series of gray stripes on a liquid crystal display (LCD) screen and placing a single pixel photoelectric detector in front of it to receive the light projected by an object.The imaging system reduces the requirements for hardware,has compact optical path and strong flexibility.It is verified theoretically that the nonlinearity between the gray scale of the image loaded on LCD and the intensity of transmitted light has no influence on reconstructed images.The effectiveness of the imaging method is confirmed experimentally.Experimental results show that after loading the stripe,it's needed to set aside certain response time,so that the detector is able to obtain accurate light intensity.Background noise and interference of conjugate image are significantly reduced and the reconstructed image quality is improved.关键词
