Abstract:This paper introduces the new type of CO2 sensor by combining optical mechanic andeletronic devices. Based on I,ambert-Beer law and using a high-quality IR detector, the gage can detectcarbon dioxide with high precision and efficiency. The detection of carbon dioxide involves some keytechniques such as current stabilization of the IR source and structure, small volume, light weight, lowpower consumption and high reliability. Meanwhile, it can be applied into many associated fields.

Abstract:This paper introduces the measuring principle of the distortion,the method of generatingstandard distortion source and the automatic measuring system with the distortion measuringinstrument and analyzes the measllring error of it.

Abstract:The paper provided the proof that tilting the Charge C0uple Device (CCD) can reducespread image and the error in measurenlent hy utilizing the basic applied optics principle and explainedthe disadvantage which Iimited the laser triangulation measuring range.

Abstract:In this paper, the total evaluation and measurement of data acquisition system isdiscussed. The two method for classifying the characters and performances of data acquisition systemare proposed.

Abstract:This paper introduces the calibrating device for the multi-function time measuringinstrument with mechanical stopuwatch, millisecond meter, electric stop-watch, time testing instrumentand so on.

Abstract:The founding standards of geometrical parameter measurement standard instrument, theexpression of uncertainty, the repeatability, confirming test and some examples are discussed in thispaper.
