英文摘要：

Measurement of curvature radius and focus length of lens using a home-made two-dimensional spectral-domain optical coherence tomography （2DOCT） system was proposed. In order to enhance the measurement precision of curva- ture radius of lens, spectrum correction method was employed in the system to reduce the energy effect due to fast Fourier transform Computation. The experimental results show that the developed 2DOCT has non-contact and non-invasive in na- ture; the system could measure the radius curvature and focus length of a lens, with high precision, using a single-shot imaging without any mechanical scanning.
