Full color single pixel imaging by using multiple input single output technology.

Abstract

In this paper, we propose a novel full color single pixel imaging by using multiple input single output (MISO) technology. In the scheme, the MISO technology, which is widely used in the wireless communications, is used to simultaneously produce three (red, green and blue) detection signal components corresponding to the red, green and blue components of the object with only one single pixel bucket detector respectively. Then, a full color image of object can be produced by synthesizing the reconstructed red, green and blue component images of object, where the red (green or blue) component image can be recovered by utilizing the speckle patterns and corresponding detection signal components. The experimental results demonstrate that our scheme can be robust against the interference of the intensity fluctuations of ambient light and improve the imaging quality. Moreover, our scheme requires only one single pixel bucket detector, which reduces the numbers of bucket detectors that need to be used. Our scheme provides a promising avenue to realize the full color single pixel imaging with MISO technology and has the potential to be extended to high quality multispectral single pixel imaging by using only one single pixel detector.
