普朗克光谱学
Planck spectroscopy
摘要：
所有光谱仪都依赖于某种机制来实现光谱选择性;常见的例子包括光栅、棱镜和带有移动反射镜的干涉仪。我们通过实验证明并验证了一种光谱技术-这里称为普朗克光谱-仅使用温度控制台和探测器测量表面的光谱发射率，而不使用任何波长选择性光学元件。普朗克光谱学涉及测量温度依赖的热发射功率，其中光谱选择性通过普朗克定律的温度和波长依赖性来实现。我们实验证明和验证了普朗克光谱在中红外线，从3到13微米的波长-主要由我们的探测器的带宽限制-分辨率约为1微米。普朗克光谱的最小设置可以使用红外相机来实现，以实现低成本的红外高光谱成像和成像椭圆偏振。
英文摘要：
All spectrometers rely on some mechanism to achieve spectral selectivity; common examples include gratings, prisms, and interferometers with moving mirrors. We experimentally demonstrated and validated a spectroscopic technique -- here dubbed Planck spectroscopy -- that measures the spectral emissivity of a surface using only a temperature-controlled stage and a detector, without any wavelength-selective optical components. Planck spectroscopy involves the measurement of temperature-dependent thermally emitted power, where the spectral selectivity is realized via the temperature- and wavelength dependence of Planck's law. We experimentally demonstrated and validated Planck spectroscopy in the mid infrared, for wavelengths from 3 to 13 um -- limited primarily by the bandwidth of our detector -- with resolution of approximately 1 um. The minimalistic setup of Planck spectroscopy can be implemented using infrared cameras to achieve low-cost infrared hyperspectral imaging and imaging ellipsometry.
