Luster is one of the vital indexes in pearl grading. To find a fast, nondestructive, and low-cost grading method, optical coherence tomography (OCT) is introduced to predict the luster grade through ...

We demonstrate a novel optical tweezers technique that enables trapping and manipulation of unusually large bubbles formed in a fluorescent dye medium using low-power laser beams. In this work, ...

For the first time, an international cadre of electrical engineers has developed a new method for photonic in-memory computing that could make optical computing a reality in the near future. The team ...
