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 ...

Calculator for Beam Waist Radius Wavelength: Focal length: Initial beam radius: (collimated input beam) Beam quality factor: (1 for Gaussian beams) Waist radius: calc Enter input values with units, where appropriate. After you have modified some inputs, click the “calc” button to recalcu...
We found that for a certain common spherical lens, there exists an optimal mirror radius of curvature (ROC), which is different from the focal lengthfof the lens and could minimize the FC-induced defocusing. Therefore, the effective FoV of the CERs can be enhanced by simply optimizing the ...
On substituting the slant angle of the moir 茅 pattern into the derived equation, the focal lengths and radius of curvatures could be determined. The experimental results successfully demonstrated the feasibility of the proposed method; the percent errors for focal length and radius of curvature ...
