Advances in optical coating technology over the past decade have made it possible to produce high-performance Raman spectroscopy filters with better reliability and at lower costs. The performance and characteristics of three typical Raman filters and an
条纹投影三维测量技术的检测精度依赖于绝对相位与深度关系的标定过程,传统的标定方法步骤复杂、用时较长,在双目测量系统中对左右相机分别标定时尤为明显。因此设计一种基于立体靶标的标定方法,靶标由两个平面组成,各个靶标平面上附着规格已知的图案,平面连接处用特殊图案标识,用于区分左右两面。立体标靶实现双目测量系统相机外部参数与相位-深度的同时标定,将标定时间减少了一半,简化了标定流程;经过实验验证,利用立体
The effects of main laser parameters, such as pulse energy, pulse duration, frequency, and work time on laser propulsion of "air-breathing mode", are investigated experimentally with a high power and high repetition frequency TEA-CO2 pulsed laser. The r
高等学校实验教学承担着培养学生实践能力、创新能力和综合素质的重要任务。传统的实验教学模式在实验内容设置和安排上缺乏对学生自主研究、深度参与及提高综合能力的考虑,因而不利于学生个性和创新精神的养成。以《光电仪器电子学实验》课程为例提出了线上线下双反馈一体化的混合式实验教学模式。通过线上线下双反馈一体化的实验教学模式,可以形成一个发现问题、及时反馈、调整实验教学方案、跟踪评价并持续改进的闭环教育过程,有效提高学生学习的自主性、积极性,提高学习效果。
A high energy pulsed terahertz (THz) laser is studied experimentally. The laser cavity simply consists of a quartz glass waveguide, a coated GaAs input window, and a crystal quartz output window. NH
Biophotonics is an exciting and fast-expanding frontier which involves the fusion of advanced photonics and biology. It has not only created many novel methodologies for biomedical research, but also achieved many significant results as an independent fie
A diode-pumped Nd:YAG oscillator laser with an end-pumped zigzag slab architecture and weak pump absorption is developed. An output power of 253 W with a slope efficiency of 50.2% and an optical-optical conversion efficiency of 39.6% is achieved from the
A retroreflector that reflects light along its incident direction has found numerous applications in photonics, but the available metasurface schemes suffer from the issue of narrow bandwidth and/or a single angle of incidence. Here, a retroreflector usin
