Single-pixel and ghost imaging

Single-pixel imaging (also referred to as ghost imaging in some cases) has evolved as an interesting alternative to focal-plane detector arrays. While detector arrays remain relevant and effective, the advantages of single-pixel systems cannot be denied. The advantages of wavelength independence and the ability to achieve compressed sensing in a multitude of domains open up avenues of research previously not accessible due to costs or systems’ complexity.

In our research, we are interested in exploring different patterns sets and setups to achieve high-resolution imaging, while investigating the applications of these systems to different research and real-world problems.
