Abstract

The Dual Optical Comb Ranging (DCR) method has the advantages of large range, fast speed and high precision, which has a wide application prospect in the field of absolute ranging. In this paper, the Mie scattering theoretical model and the key parameters of atmospheric refractive index which affect the ranging accuracy of the DCR system are studied numerically. The effects of the relative size and refractive index of the Mie scattering particles on the ranging accuracy are simulated. The numerical results show that with the increase of the relative size and refractive index, the loss of light energy is greater, resulting in the reduction of the Signal to Noise Ratio (SNR) of the ranging results. The influence of atmospheric refractive index on ranging results is also simulated, and the influence of atmospheric temperature jitter on ranging is 2.9033 μm/(m∙°C), atmospheric pressure jitter on ranging is 8.203 μm /(m∙kPa), atmospheric humidity on ranging is 3.7676 μm for 1m ranging target with 1% humidity jitter, and atmospheric carbon dioxide on ranging is 1.45×10^-4 μm /(m∙ppm).
