WAVELENGTH MEASURING SYSTEM |
摘要 |
A method for measuring the wavelength of light, particularly short pulses of light, with improved accuracy comprises passing the light down a backscatter medium such as an optical fiber and detecting and measuring the wavelength of the backscattered light which will have a pulse length of potentially far greater length than that of the initial pulse. The use of interferometers in conjunction with a reference light of known wavelength enables very accurate measurements to be made. |
