Abstract
A method of linearly coded profilometry is proposed. It uses linear-structure light with isosceles triangle teeth to code the object being measured and a phase-shifting technique to decode the profile. For reducing the effect of noise more than three equally spaced samples are used, and, according to the least-squares method, the general formulas of the decoded phase are given. The experimental results of a model of a head are shown.
