A team of researchers led by Takuo Tanemura at the University of Tokyo, Japan, has demonstrated the use of a multimode fiber (MMF) in combination with an integrated optical phased array (OPA) chip for single-pixel imaging in potential biomedical applications, the company said.
Taichiro Fukui, a PhD student in the group, will present their imaging technique at the Optical Fiber Communication Conference and Exhibition (OFC), to be held 8-12 March 2020 at the San Diego Convention Center, California, USA.
According to Fukui, previous research has shown that illuminating a target using random speckles rather than a focused spot enhances the spatial resolution of an imaging process.
By integrating an MMF output with an OPA chip, which splits the input light into a number of independent phase shifters, the group was able to generate different random speckle patterns to illuminate the target.
The Optical Fiber Communication Conference and Exhibition (OFC) is the largest global conference and exhibition for optical communications and networking professionals.
Founded in 1916, The Optical Society (OSA) is the professional organization for scientists, engineers, students and business leaders who fuel discoveries, shape real-life applications and accelerate achievements in the science of light. For more information, visit osa.org.
