摘要:
Systems and methods for generating, projecting or correlating thermal spectra use digital micro-mirror devices (DMDs) to controllably modulate input radiation such as long wave infrared light. An optical system for creating an output spectrum based upon an input light suitably includes a grating configured receive the input light and to spread the input light by wavelength into an input spectrum. A digital micro-mirror device (DMD) is configured to receive the input spectrum and to controllably activate mirrors in the DMD corresponding to selected wavelengths of the input light. Portions of the input light having selected wavelengths can be extracted from remaining portions of the input light for the output spectrum. By selecting and activating only certain mirrors on the DMD, particular wavelengths of light in infrared or other spectra can be optically switched for any number of subsequent applications, including spectral projection, simulation of solar or other spectra, detection of chemical substances, or the like.

用于产生,投影或相关热谱的系统和方法使用数字微镜器件(DMD)来可控地调制诸如长波红外光的输入辐射。 用于基于输入光产生输出光谱的光学系统适当地包括被配置为接收输入光并将波长的输入光扩展成输入光谱的光栅。 数字微镜装置(DMD)被配置为接收输入光谱并且可控地激活对应于输入光的所选波长的DMD中的反射镜。 可以从用于输出光谱的输入光的剩余部分中提取具有所选波长的输入光的部分。 通过仅选择和激活DMD上的某些反射镜,红外线或其他光谱中的特定波长的光可以被光学切换以用于任何数量的后续应用,包括光谱投影,太阳能或其它光谱的模拟,化学物质的检测等 。
