Improving the accuracy of hybrid scanning 3D fiber-optic measuring heads with an acousto-optic feedback sensor for contact and non-contact coordinate measurements of product sizes
The article presents a method for determining the elastic deformations arising from the mechanical contact of a spherical tip and a product, which makes it possible to exclude the influence of material deformations like «pile-up». Paper discusses the construction of a hybrid 3D scanning fiber-op...

| Summary: | The article presents a method for determining the elastic
deformations arising from the mechanical contact of a spherical
tip and a product, which makes it possible to exclude the
influence of material deformations like «pile-up». Paper discusses
the construction of a hybrid 3D scanning fiber-optic measuring
head (FOMH) with the formation of scanning laser beam motion
within the angular sector of the 180°×180° hemisphere based on a
low-coherence interferometer, a spatial light modulator based on
a fiber-optic piezoscanner and a «fisheye» lens. The possibilities of
high-precision two-coordinate measurements of the scanning laser
beam due to the use of an acousto-optic modulator in the FOMH
feedback sensor as a space-sensitive transducer are considered. |
