Hadamard transform spectrometry (HTS) using a liquid crystal spatial light modulator (LC-SLM) as a stationary encoding mask is shown to be a viable technique for visible and Raman spectrometry. HTS is a multiplexing method that has many advantages similar to Fourier transform spectrometry. This paper analyzes the systematic errors in Hadamard transform optical instruments caused by moving. masks, incorrect. mask alignment, faulty mask fabrication, missing data, diffraction, etc. and Estimated Reading Time: 4 mins.  · Hadamard Transform Optics focuses on Hadamard transform optics and Hadamard encoded optical instruments. The techniques developed to date are described, and a unified mathematical treatment that should facilitate comparisons between different classes of .

A brief introduction to Hadamard transform (HT) techniques is presented to show that the DMA may be the best Hadamard encoding mask yet developed. A comparison of a conventional raster scanning (CRS) scan and a Hadamard transform spectrometry (HTS) scan with respect to the Hadamard multiplex advantage using a nonphoton noise-limited, single. In this paper, a single-pixel mid-infrared (mid-IR) Hadamard transform spectrometer is developed. The spectrometer's design, fabrication and experimental results are discussed. The single-pixel mid-IR Hadamard transform spectrometer has dual cascaded encoding regions, nm to nm and nm to nm, to reduce the travel range required by the moving mask. Hadamard transform spectrometry (HTS) using a liquid crystal spatial light modulator (LC-SLM) as a stationary encoding mask is shown to be a viable technique for visible and Raman spectrometry. HTS is a multiplexing method that has many advantages similar to Fourier transform spectrometry.

Systematic errors in Hadamard transform optics N. J. A. Sloane, Martin Harwit, and Ming-Hing Tai This paper analyzes the systematic errors in Hadamard transform optical instruments caused by moving masks, incorrect mask alignment, faulty mask fabrication, missing data, diffraction, etc. and describes tech-.

The paper presents a novel kind of Hadamard transform optic. First investigations are made with a micro mirror array in a Hadamard transform spectrometer (HTS) whereby the usually used detector array is replaced by the micro mirror array. All the mirrors are imaged onto a single detector. The measurement is performed using a Hadamard matrix, i.e. while each detector reading a certain.
