The dimensional measurement using CCD imaging sensors isusually implemented by the method of photoelectrical pulse number counting,in which a photoelectrical pulse represents a span of photoelectrical cell inCCD imaging sensor. The span is approximately equal to the resolu tion errorof dimensional measurement. In many cases of highly precise measurement, this kind of resolution error limited the application of this technology. In or-der to surmount the difficulty, D. G. Purll has suggested that the pulse signalbe demodulated to reform the continue photo signal by which the characteristicedge point of a measured object might be determined. This paper has theoreti-cally analysed the method of demodulation measurement. At first. it analys-ed the engineering realization of the ideal demodulation network and resultedin that (1) adjusting the lens parameter D/_2 could meet the band widthrequirement of photo signal; (2) in the specified condition, ideal demodulationnetwork could be replaced by an ideal low-pass filter; (3) the linear phasecharacter of this filter is very important to demodulate the pulse signal exac-tly; and (4) the definite length of CCD array merely affects the measure-ment range, whereas does not affect the demodulation precision. And then, itproved that the characteristic edge point is located at the point of the max-imum differential value of the continue photo signal. According to these analy-ses, the signal processing method has been, for the first, put forward. Arealizcd, experimental measurement system using this demodulation methoddemonstrated that this method could raise the resolution about ten times.Through the showed measurement result, it can be seen that because of the riseof resolution, systematic error appeared as an approximate straight line.This feature will be useful to compensate the systematic error by microproce-ssor. In this way, the demodulation measurement technique can reach theprecision level that in the total measurement range equal to the length of CCDarray, the measurement error can be under 2μm.
