ON THE IMPLEMENTATION OF HADAMARD SPECTROSCOPY
UNIVERSITY POLITEHNICA OF BUCHAREST SCIENTIFIC BULLETIN-SERIES A-APPLIED MATHEMATICS AND PHYSICS（2015）
Abstract
In this paper we present the theory of Hadamard spectroscopy and an experimental implementation of it in the visible range of the spectrum, more precisely for the spectrum of a helium lamp. A mechanical mask with 13 elements is used to implement Hadamard spectrometry, resulting in just 7 samples for the recovered spectrum. The advantages and drawbacks of using such a mechanical mask are presented as well as alternatives for improvement.
