Method of light power selection in LCCD vertical target measurement system with laser light

Both factors which influent LCCD imaging and reflective ruler which measured object follows were analyzed in detail.With this understanding,models of LCCD imaging capability and object reflective energy were built respectively.Based on these,the formula of light power selection of LCCD measurement system with laser light was derived.Ultimately,the imaging experimentation with line LCCD camera and line laser on measured object was done.And the result shows that the model of light power selection is correct.
