Signal process in a novel system for nano-displacement measurement based on optical lever;

Study on a nanometer system for displacement measurement based on optical lever;

Research on the measurement of the Young′s modulus system by photoelectric optical lever;

Using light lever to measure the thickness of sheet;

In this paper the main problems existing in the experiment, which use light lever to measure metal linear expansion coefficient, are studied.

This paper presents the structure of a new light lever-reflectinglight lever, and conducts acomparison experiment of Young s elastic modulus measured by the new and old light lever respectivelyand gives measuring results and error.

The paper detail introduces the work principle of the test system of rocket,deduces the formula and the magnification of optical lever.

A new electrostriction material strain measure method using optical lever has been proposed.

The attitude angle of high-speed mobile object in the shield tube is tested by use of optical lever in this paper.

Since the change of micro distance cause the change of reflected spot on the position sersor diode,the change of micro distance could be tested by testing the coordinate X,Y in the position sensor diode.
