Novel Hadamard transform spectrometer realized using a dynamically driven micro mirror array as light modulator

摘要

The paper deals with a novel setup of a Hadamard transform spectrometer (HTS) which encoding mask is realized by arnmicro mirror array. In contrast to other applications of an HTS the mirrors of the array are not statically switched butrndynamically driven to oscillate at the same frequency. The Hadamard transform is obtained by shifting the phase shift ofrnoscillation. The paper gives a brief introduction in the entity of the Hadamard transform technique. The driving andrndetection circuits are presented and first measurement results are discussed.
