We introduce a modifying deflectometry method to reduce parasitic ghost signal noises in transparent optical testing. The proposed approach shows adjusting the screen distance and displayed screen pattern to shrink the light from undesired surfaces’ reflection. The flexibility of deflectometry optical layout allows huge adjustment availability while keeping the optical testing capability and suppressing the parasite signal. Moreover, the customized fringe pattern could shine the desired surface only effectively. Ray tracing simulation shows the best system formation, and the modified experimental setup confirms the proposed method for various types of optics testing. Lastly, we discuss the limitations of the method.
