That is achieved by combining the reflected light from the lighted object for measurement through First lens And a corresponding reference light Include a scavenging unit that has been outlined in order to receive Arrangement on the optical path of the light for measurement. And to beam the measurement light onto the second lens that is outlined so that it is positioned between the scanning units. And the first lens on the path Optical of measuring light, a branching unit arranged so that it is positioned between the first lenses. And the second lens And make the optical path of light for branch measurement to be optical path For observation to observe objects Where the second lens and the scouring unit will be positioned. To maintain the angle of incidence of light for measurements that were scanned by branch screed units. Of light That is achieved by combining the reflected light from the lighted object for measurement through First lens And a corresponding reference light Include a scavenging unit that has been outlined in order to receive Arrangement on the optical path of the light for measurement. And to beam the measurement light onto the second lens that is outlined so that it is positioned between the scanning units. And the first lens on the path Optical of light for measurement, branching units arranged between them so that they are placed between the first lenses. And the second lens And make the optical path of light for branching measurement into a light path For observations to observe objects Where the second lens and the scouring unit will be positioned. To maintain the angle of incidence of light for measurements that were scanned by a series of scavings on a branching unit. -------------------------------------------------- -------------------------------------------------- ------------------- Optical cross-section screed that produces a cross-section of an object based on Of light that is obtained by combining the reflected light from an object that has been projected with light for Measured through the first lens And a corresponding reference light Included with a set of organized scavings to provide Are provided on the optical path of the light for measurement. And to scorch the measurement light onto a second lens that is outlined so that it is placed between the scanning sets.
