Abstract
A variable modulated transfer function (MTF) design employing a variable gate voltage source for use in inspecting specimens is disclosed. The design applies a variable gate voltage to each pixel of a sensor, wherein applying the variable gate voltage to each pixel adjusts the MTF of the pixel. MTF adjustment improves adverse effects encountered during inspection, such as aliasing and maintaining contrast.
