  Night vision is the ability to see in low-light conditions. However,
conventional night vision imaging technology is limited by the requisite
high-performance infrared focal plane array. In this article, we propose a
novel scheme of color night vision imaging without the use of an infrared focal
plane array. In the experimental device, the two-wavelength infrared laser beam
reflected by the target is modulated by a spatial light modulator, and the
output light is detected by a photomultiplier tube. Two infrared night vision
images are reconstructed by measuring the second-order intensity correlation
function between two light fields. Thus, the processing mode of optical
electric detection in conventional night vision imaging is transformed into the
processing mode of light field control. Furthermore, two gray images with
different spectra are processed to form a color night vision image. We show
that a high-quality color night vision image can be obtained by this method.
