Digital Micromirrors

The possibility of an all-digital (sourceto-eye) projection display was realized in 1987 with the invention of the Digital Micromirror Device™ projection display chip at Texas Instruments (TI). The DMD™ chip is a microelectromechanical systems (MEMS) array of fast digital micromirrors, monolithically integrated onto and controlled by an underlying silicon memory chip. Digital Light Processing™ projection displays are based on the DMD chip. DLP™ projection displays present bright, seamless images to the eye that have high image fidelity, and stability.

The Impact

In the Hadamard transform (HT) near-infrared (NIR) spectrometer, there are defects that can create a nonuniform distribution of spectral energy, significantly influencing the absorbance of the whole spectrum, generating stray light, and making the signal-to-noise ratio (SNR) of the spectrum inconsistent. To address this issue and improve the performance of the digital micromirror device (DMD) Hadamard transform near-infrared spectrometer, a split waveband scan mode is proposed to mitigate the impact of the stray light, and a new Hadamard mask of variable-width stripes is put forward to improve the SNR of the spectrometer. The results of the simulations and experiments indicate that by the new scan mode and Hadamard mask, the influence of stray light is restrained and reduced. In addition, the SNR of the spectrometer also is increased.
