英文摘要：

The optical spectral characteristics of pig leather, ox leather and sheep leather were measured with terahertz time-domain spectroscopy （THz-TDS） in the range of 0. 2 - 1. 7 THz at room temperature. By measuring the optical parameters of the leathers such as absorption coefficient, refractive index, etc, their components were analyzed and their qualities were assessed. The absorption peaks of three leather samples were found clearly. The results show that THz-TDS can be employed to detect leather＇s components quickly.
