1. A method for inspecting an object for defects comprising: obtaining reflectivity of each of a plurality of regions on the object; determining an amplification ratio for each of the regions based on the reflectivity of each of the regions; irradiating a light onto the plurality of regions; amplifying a light reflected from a first region by a first amplification ratio that is determined for the first region; detecting whether the irradiated light has been transferred from the first region to a second region; amplifying a light reflected from the second region by a second amplification ratio that is determined for the second region; and analyzing the amplified lights from the first region and the second region to determine the existence of a defect on the object.
