| Abstract: | A light interference measurement system of youngs modulus for material is designed, Taking carbon steel as a example, the measurement predsion of the system is tested. The measured results and the standard values of young's modulus for material are compared. The results show that the meaurement predsion of the system enhanced to 0.1 per cent. |
