A novel microscopic imaging technique, developed by Brown University engineers to capture 3D images using quantum entanglement, may finally solve the problem of phase wrapping.
Undergraduate students Moe (Yameng) Zhang and Wenyu Liu presented their work at the recent Conference on Lasers and Electro-Optics. They worked on an independent project under the supervision of senior research associate Petr Moroshkin and Professor Jimmy Xu.
The new concept utilizes two light spectra: infrared light to illuminate the target, which is then imaged using visible light entangled with the infrared. This process advances microscopic imaging by capturing the intensity and phase of light, producing true holographic images.
“We introduce Quantum Multi-Wavelength Holography,” said Zhang, a junior concentrating in engineering physics at Brown. “The technique allows us to gather better and more accurate information on the thickness of the object, which enables us to create accurate 3D images using indirect photons.”
“You could call this infrared imaging without an infrared camera,” Xu said. “It sounds impossible, but they did it. And they did it in a way that enables great depth resolution in the images it produces.”
