Optical technique for porosity detection inside valve body spool bores down to 5 mm diameter

Optical technique for porosity detection inside valve body spool bores down to 5 mm diameter

We inspect inner surfaces of valve body spool bores down to 5 mm diameter for porosity defects, using an optical probe with ~50 μm lateral resolution. The probe can also distinguish porosity from bump-type defects.
