Compensation for the decrease of output SNR of hadamard transform spectrometer with nonideal mask
비이상적 마스크로 인한 하다마드변환 스펙트럼 검파기 출력값의 신호대 잡음비 감소의 해결방안
Abstract
When we use Hadamard transform spectrometers (HTS), we can increase signal to noise ratio(SNR) by multiplexing which is done by masks. But if the mask has a single defective element, output-SNR decreases. In this paper the effect of a single defective element on the output-SNR is investigated. And a method of compensating for the defective mask element is presented.
