Halide perovskites have been widely explored as efficient photo-responsive materials for applications in many optoelectronics areas owing to their unique optoelectronic properties and facile processing. However, the poor stability of these materials is still a substantial challenge for their commercialization.
Bilateral teleoperation system has been applied in numerous fields such as surgery, explosive removal and construction machinery. Good transparency (position tracking and force feedback) is an important performance index in the control design of bilateral teleoperation systems. How to improve the transparency of the bilateral teleoperation system has been the key and hot issue in the field.
The SPIDER (the Segmented Planar Imaging Detector for Electro-optical Reconnaissance) imager has attracted intensive attention because of its superior imaging performance and structural compactness. This new imaging method has been proposed based on standard imaging interferometer techniques. Through introducing photonic integrated circuits (PICs) and replacing bulk lens systems with compact lenslets array, the SPIDER is estimated to reduce size, weight, and power (SWaP) by about ten to hundred times for a similar resolution compared with conventional diffraction-limited optical systems.
Recently, the liquid crystal adaptive optics research team from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences (CAS) has built a high-density integrated beam array generation system using Liquid Crystal Optical Phased Array (LCOPA). The number of sub-beams in the integrated beam array is 40×40, and the average pointing accuracy is less than 20μrad. This study is published on Optics Communications.
Metal surfaces are vulnerable to pitting and peeling failures in deep seawater due to aggressive corrosive ions, which can hamper their usage for marine applications. Therefore, anticorrosion research on industrial metallic surfaces to avoid the seawater corrosive ion interaction has great life-saving and economic significance.
In recent years, micro-LED displays have attracted increasing research and commercial attention because of their unique advantages, including high resolution, low power consumption, high brightness, and flexibility. In order to meet the application requirements of full-color micro-LED display, it is necessary to optimize the fabrication process to produce high-performance display devices.
