| Abstract: | In this paper the main problems existing in the experiment, which use light lever to measure metal linear expansion coefficient, are studied. Improved measure method using splitter interference is put forward. It not only avoid the existing problem but also connect CCD technique and splitter interference with the measurement of metal lir:ear expansion coefficient.The new measure method has many good character, such as intuition character, high sensibility, high precision,and so on.This method is a new way of study metal linear expansion coefficient,and can help st 'dents to improve their synthetic ability of knowledge and experiment. |
