通过热调制下的光谱分析，研究了液晶盒的组合对选择波长的影响。利用具有不同螺旋扭转力（HTP）大小和符号的手性掺杂剂，形成了几种CLC盒。不同温度依赖性的CLC电池的组合表明，当温度从25 °C增加到45 °C时，大于700nm的红外光范围被广泛反射，可见光几乎没有调制。结果表明，选择性透射光谱的热调制是可控的CLC细胞与不同的温度依赖性的组合。
The effects of the combination of cholesteric liquid crystal (CLC) cells on selective wavelength are investigated by the spectroscopic analysis under thermal modulation. The several kinds of CLC cells are formed by using the chiral dopants with different magnitudes and signs of helical twisting power (HTP). The combination of CLC cells with different temperature dependence shows that the infrared light range longer than 700nm is widely reflected and the visible light is little modulated when the temperature increase from 25 °C to 45 °C. The results demonstrate that the thermal modulation of selective transmittance spectra is controllable by the combination of CLC cells with different temperature dependence.
