The advanced equipment manufacturing industry demands high-precision, versatile, and multi-dimensional geometric measurements. Multi-channel laser ranging technology offers a unified sensing approach, minimal error sources, and high measurement efficiency. Frequency modulated continuous wave (FMCW) laser measurement technology, with its high precision, wide dynamic range, strong anti-interference capability, and high signal-to-noise ratio, enables precise absolute distance measurements of large-

Researchers from Peking University Yangtze Delta Institute of Optoelectronics, have proposed a universal design scheme for discrete whispering gallery mode (WGM) microcavity devices. The developed devices achieve an exceptional quality factor (Q) of up to 1 billion while maintaining remarkable robustness. On this platform, the team has successfully demonstrated low-threshold (4mW) and low-noise (-103dBc/Hz10kHz) soliton microcombs. This groundbreaking research provides an innovative technologica

Optical frequency combs (OFCs) are characterized by a comb-like structure in the frequency domain, where the frequency spacing between the comb teeth is equal, and the phases are mutually locked. OFCs have widespread applications in precision measurements, spectroscopy, and optical communications. In particular, in the field of microwave photonics, optical frequency combs serve as a bridge linking the optical frequency domain and the radio frequency (RF) domain. Among various OFC generation tech

Single-pixel imaging is an emerging computational imaging technology that, in contrast to traditional array detector imaging, utilizes a single point detector without spatial resolution capability to record image information. The single-point detector offers significant advantages, including low dark noise, high sensitivity, rapid response, and lower cost, while exhibiting excellent performance across nearly the entire spectral range. Due to its unique imaging mechanism, single-pixel imaging has
