设 sin x + sin 2x 的周期是p 则sin(x + p) + sin[2(x + p)] = sin x + sin 2x sin(x + p) + sin(2x + 2p) = sin x + sin 2x 固知p和2p都是2π的倍数=>p的最小值是2π 对sin mx + sin nx 。设周期是p 则sin(mx + mp) + sin(nx + np) = sin mx + ...
Given a sine-wave of the formx = a sin(b(t+c)) + d, the period of the sine-wave is obtained as2 * pi / b. Sinceb=1(or by visual inspection), the period of our sine wave is2 * pi. I can check the results obtained from other methods against this baseline. ...

Based on the period of the grating, we can classify the FBGs into two types: short period grating (SPG) and long period grating (LPG). A grating is called an SPG when the period of the grating is less than the optical wavelength, which is on the order of 1.3–1.6 μm. For typical...
