Abstract
With the chromatic length aberration (CLA) technique, imaging of surfaces with complex three dimensional geometry is possible. Analysis of sample sizes in micro or nanometer scale is an added advantage available with CLA system. This article describes the methodology adopted for establishing the CLA technique for characterizing selected ceramic/ceramic coated substrates used in cardiovascular and orthopedic applications. The measurement of surface finish and coating thickness were validated against benchmarked technologies based on atomic force microscopy (AFM), stylus profilometry and standard ball cratering methods. Results of measurements were statistically analyzed by Student t test and reported the two tail p values to compare the results from different measurements techniques
