METHOD FOR DETERMINING THE RESIDUAL sphericity REFLECTING SURFACE

摘要

1. A method for determining the residual spherical reflective surface, which consists in that the measuring device is installed in operational position in front of the reflecting surface located in a vertical plane and is adapted to autocollimating image, characterized in that as a measuring device using at least one autocollimation theodolite, the residual spherical is determined by measuring the angular value read on the vertical circle of a theodolite theodolite grid when combining with her car ollimatsionnym image angle measurement is performed for the two points of the reflecting surface maximally spaced surfaces and located on the same vertical line, and the residual sphericity was calculated according to the formula: where: Δd - difference installation heights of the theodolite relative to the earth, m, α, β - values ​​of the vertical angles theodolite range when combined with the grid of a theodolite autocollimation her image for the upper and lower position of the theodolite respectively Grad 2. Method of determining the residual spherical reflecting surface according to claim 1, characterized in that a theodolite with a compensator of Vertical zero.
