Abstract

A miniaturized tuneable light source using a white LED and a Fastie-Ebert configuration of a mini-spectrometer is demonstrated. In this work, the CMOS sensor in the Fastie-Ebert configuration is replaced with a DLP2010 0.2 WVGA Digital Micromirror Device (DMD). Experimentally, 36 wavelengths within the range of 615 nm to 685 nm were tuned by changing the pattern on the DMD and activating 10 columns of mirrors. This resulted in narrow spectral lines with a FWHM between 3.24 nm and 5.85 nm. The demonstrated optical performance experimentally showcases perspectives of developing a programmable miniaturized broadband tuneable light source based on a DMD while going towards miniaturization.
