Image acquisition method for twin blades of turbine; has displacement carriage positioned with respect to rotary table to acquire images of each individual blade

摘要

The method involves moving twin blades (10) positioned on a rotary plate synchronized with a digital line camera (2). The blades are mounted using an eccentrically mounted rotary table (3) with axes parallel to the plate axis and the blade axes. The blades are mounted on a displacement carriage (13) positioned differently from the rotary table that is positioned with respect to the rotary table to acquire successive images of each blade (11,12). The rotation speed of the rotary table is synchronized in a nonlinear manner with the uniform rotation of the rotary plate according to patent application 198 32 322.0.
