Abstract
Optical designers typically use aberration diagrams based on ray tracing to analyze the chromatic aberration performance of their optical system. However to evaluate the impact of chromatic aberrations on color fringes in images optical imaging simulations are necessary including the effect of spectral response of the sensor or film, exposure time, Gamma corrections, etc. We have analyzed the correspondence of classical chromatic aberration measures versus analysis based on image simulations. We propose a metric directly linked to color fringes in images which can be used to constrain and specify the chromatic aberration performance of an optical system.
