In this paper we used digital in-line holography to measure defocus aberration of wavefront. Object’s position can be measured by digital in-line holography. Defocus aberration causes errors in the range finding. We showed that the range finding error can be measured by wavefront defocus aberration. Finally, we compared the results of in-line digital holography with the results obtained from Hartmann wavefront sensor.

Keywords: Defocus aberration, Hologram, Digital in-line holography, wavefront, Hartmann sensor
