Recently, a research team from the Aerospace Laser Technology and Systems Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, proposed a new holographic imaging technology using frequency domain direct sampling. The relevant results were published in Optics Letters under the title of "Fourier inspired single pixel holography".Digital holography is a tech...
Researchers at the University of Rochester have created new micro comb lasers that go beyond previous limitations and have simple designs suitable for various applications. The research results are published in Nature Communications.Optical frequency combs are optical measurement instruments that have revolutionized atomic clocks, spectroscopy, metrology, and other fields. However, the difficulty ...
Hybrid 3D integrated optical transceiver. (A, B) Test setup: Place the photon chip (PIC) on the circuit board (green), and glue the electronic chip (EIC) onto the top of the photon chip. (C) It is the cross-section of the EIC-PIC component with micro protrusions. (D) Display the mesh of the finite element model.The latest progress in artificial intelligence, more specifically, is the pressure plac...
It is reported that researchers from Foshan University, the Institute of Chemical Defense of the Academy of Military Sciences, the National Defense Technology Key Laboratory of Equipment Remanufacturing Technology of the Armored Forces Academy, and Chengdu State owned Jinjiang Machinery Factory have summarized and reported the latest progress of machine learning in defect detection and prediction ...
Photoacoustic technology provides a non-invasive method for detecting biological tissues, but its clinical application is limited, partly due to the large volume and high cost of laser sources. A compact PA sensing instrument powered by laser diodes for biomedical tissue diagnosis can provide clinical doctors with a practical and effective tool for evaluating breast diseases.By providing a cost-ef...
