摘要：
Angular Speckle Contouring (ASC) allows the measurement of microscopic (roughness) and macroscopic form (shape). ASC is a fast, non-contacting and full-field measurement technique. The measurements for shape and roughness are performed for measuring a piston of internal combustion engine. All measurements have been carried out without vibration isolation of the optical tables. For the shape measurements the surface has been treated with white powder to increase the contrast, for the roughness measurements the surface hasn't been treated. The results obtained by ASC are compared with mechanic-profilometric measurements and the results are discussed.
