| Abstract: | The fundamental law of the phase method for noncontact whole-field 3-D curved surface measuring is briefly described. Having studied the influence of the slopes of measured surfaces on the spectral filter in the frequency domain,a formula for calculating the maximum measurable slopes is developed and verified by measuring a cone surface. |
