Fourier transform infrared (FT-IR) attenuated total reflection (ATR) imaging has been successfully used to identify individual mineral components of ancient Maya paint. The high spatial resolution of a micro FT-IR-ATR system in combination with a focal plane array detector has allowed individual particles in the paint to be resolved and identified from their spectra. This system has been used in combination with micro-Raman spectroscopy to characterize the paint, which was found to be a mixture of hematite and silicate particles with minor amounts of calcite, carbon, and magnetite particles in a sub-micrometer hematite and calcite matrix. The underlying stucco was also investigated and found to be a combination of calcite with fine carbon particles, making a dark sub-ground for the paint.
傅里叶变换红外（FT-IR）衰减全反射（ATR）成像已成功用于识别古代玛雅颜料中的各个矿物成分。微型傅里叶变换红外衰减全反射（FT-IR-ATR）系统的高空间分辨率与焦平面阵列探测器相结合，使得能够从颜料中的光谱分辨并识别单个颗粒。该系统已与显微拉曼光谱联用，用于表征这种颜料，结果发现它是赤铁矿和硅酸盐颗粒的混合物，在亚微米级的赤铁矿和方解石基质中含有少量方解石、碳和磁铁矿颗粒。还对底层灰泥进行了研究，发现它是方解石与细碳颗粒的组合，形成了颜料的深色底层。
