b. the focal lengthc. twice the focal lengthd. half the focal length 相关知识点: 试题来源: 解析 答案C设抛物线方程为x^2=2py 符合该方程的平抛运动的参数方程为:y=1/2gt^2,x=vt 改写参数方程得:y=2gx^2/v^2 于是2p=v^2/2g 在最高点有R=v^2/g 得R=P 即焦距的两倍....
A procedure for the measurement of focal length and radius of curvature of a lens using coherent gradient sensing system and Fourier transform fringe analysis technique has been demonstrated. Light from the laser illuminates the specimen and the wavefront emerging from the specimen is tested using ...

To realise such monolithic diamond Raman laser, the optimisation of the fabrication process is of critical importance since the Raman cavity mode is primarily defined by the micro-lens structure [9]. A large cavity mode, and hence a large radius of curvature (ROC) (> 10 mm) micro-lens, di...
