Abstract

We developed a novel spectrum simulating light source that uses a high brightness Laser-Driven Light Source (LDLS) and high throughput, spectrally programable light engine to deliver high fidelity spectrum matching between 380 nm and 780 nm. The light source leverages the tunability of a digital micromirror device (DMD) with characterization algorithms to produce open-loop spectral matched light output. A monitoring spectrometer is not necessary for matching preloaded target spectra after an initial characterization of the system transfer function. The reported light source can match spectral lines down to 4.5 nm full-width-half-maximum (FWHM) linewidth and simulate the detailed spectral profiles of compact fluorescent lamps with high fidelity. With a 380 nm to 780 nm wavelength range, the source can be a valuable tool for sensor calibration, hyperspectral imaging, and medical-related research.
