Abstract
In an encoding period of Hadamard Transform Optics (HTO), the instable effect of the source (or signals) on the image or spectrum is studied to decrease aberration of the image or spectrum. The effect is due to the light intensity(or signals) fluctuation coupling to intermediate measurement values in the encoding period of HTO. The sensitivity of the effect to the frequency and amplitude of the fluctuation is also shown. The study reveals that the sensitivity has accumulative and cyclic nature, and it is an intrinsic characteristic of HTO. It limits the instability and inhomogeneity levels of the light source(or instability level of signals). The intrinsic characteristic can also be used to improve and analyze the image and spectrum which is given by HTO.
