The degradation of image quality in space-based remote sensing is a critical challenge due to atmospheric disturbances. In this paper, we propose a new model to simulate image blur effects caused by turbulence and aerosol scatteri

Photon-level single-pixel imaging overcomes the reliance of traditional imaging techniques on large-scale array detectors, offering the advantages such as high sensitivity, high resolution, and efficient photon utilization. In thi

In this work, we achieve a fourfold enhancement in thermo-optic coefficient measurement resolution for KTiOPO4 crystal using a self-stabilized birefringence interferometer integrated with cascaded second-harmonic generation. We ob

Hybrid integrated external cavity lasers (ECLs) using cascaded micro-rings with the advantages of a wide tunable range and a narrow linewidth have rich applications. However, due to the limited bandwidth of the reflector, continuo

The growing demand for broadband near-infrared (NIR) irradiation in security, biomedicine, and food science is driving the development of new NIR light sources. Herein, a series of Cr3+/Ni2+ co-doped transparent glass ceramics con
