Abstract

In this paper, we present a doubly-encoded single-pixel Hadamard transform spectrometer that has its spectral resolution decoupled from its throughput. The proof-of-concept is designed in the 1500 nm to 1600 nm near-infrared (NIR) wavelength range and uses a digital micromirror device (DMD) in conjunction with a fixed mask for encoding. The proposed system can easily be extended to other infrared (IR) wavelengths to achieve maximum throughput and multiplexing advantage.
