- Abstract
Based on the principle of low coherent light interference of optical fiber, a new method for detecting the distance between the mirror surfaces of a compound lens is proposed. Firstly, a system based on the principle of low coherent light interference is designed. Secondly, the frequency calculation method of interference signal of measurement system is put forward, and the band-pass filter is designed for interference signal to improve the signal-to-noise ratios. Based on the characteristics of low coherence light interference signal, the least squares symmetric peak location algorithm is proposed, which realizes the precise locating of the peak of the interferometric signal. Besides, the experiment of measuring the distance between the compound lens is carried out and the measurement error is analyzed.
