The real-time measurement of the polarization and phase information of light is very important and desirable in optics. Metasurfaces can be used to achieve flexible wavefront control and can therefore be used to replace traditional optical elements t
Self-imaging is an important function for signal transport, distribution, and processing in integrated optics, which is usually implemented by multimode interference or diffractive imaging process. However, these processes suffer from the resolution
Despite the unique advantages of optical microscopy for molecular specific high resolution imaging of living structure in both space and time, current applications are mostly limited to research settings. This is due to the aberrations and multiple s
We propose a new optical profilometer for three-dimensional (3D) surface profile measurement in real time. The deviation angle is based on geometrical optics and is proportional to the apex angle of a test plate. Measuring the reflectivity of a paral
针对现有的无参考复原遥感图像质量评价方法特征提取不够充分的问题，文中提出一种融合多特征的无参考复原遥感图像质量评价算法GEDIQA（No-Reference Recovered Remote Sensing Image Quality Assessment Based On Fusion of Multiple Features （Gradient、Entropy and Difference Images），GEDIQA）。在复原遥感图像上，提取梯度特征、频域熵特征、差分图特征，并利用Adab
