摘要： In certain embodiments, an optical device and a method of use is provided. The optical device includes a fiber Bragg grating having a substantially periodic refractive index modulation along a length of the fiber Bragg grating. The fiber Bragg grating has a power transmission spectrum with a plurality of local transmission minima, wherein each pair of neighboring local transmission minima has a local transmission maximum therebetween. The local transmission maximum has a maximum power at a transmission peak wavelength. The optical device further includes a narrowband optical source in optical communication with a first optical path and a second optical path. The narrowband optical source is configured to generate light having a wavelength at or in the vicinity of a local transmission maximum or at or in the vicinity of a wavelength at which the power transmission spectrum has a maximum slope between a local transmission maximum and either one of two local transmission minima neighboring the local transmission maximum.

摘要： A control system of transferring pulse width modulation for a cooling fan motor includes an input end of pulse width modulation, a transfer unit, a transfer unit and a drive circuit. The input end of pulse width modulation is for inputting pulse width modulation signal. The transfer unit is connected to the input end and transforms the pulse width modulation signal as analog voltage signals in different reference levels based on different duty cycles of the pulse with modulation signal. The drive circuit controls rotational speed of the fan motor based on the analog voltage signals in different levels.
