Abstract

We report performance measurements of a photodiode array Hadamard transform spectrometer (HTS) with a stationary entrance mask. The high throughput of the multi-slit, no- moving parts instrument is shown to yield a significantly higher S/N ratio than a single-slit array spectrometer. In addition, we examine sources of instrument noise and propose techniques to further enhance system performance.
