In imaging, the detection of light originating from multiple scattering, indirect reflections and surrounding backgrounds are known to produce errors especially in intensity-ratio based measurements. SLIPI (Structured Laser Illumination Planar Imaging) is an imaging technique that significantly reduces the impact of such issues. In this study, SLIPI is combined with the two-color LIF (Laser Induced Fluorescence) ratio thermometry approach for measuring water temperature in both a cuvette and a hollow-cone spray. By removing the unwanted background interferences using SLIPI, we observe both significant improvements in terms of temperature sensitivity as well as more pronounced temperature gradients within the spray.
在成像过程中，已知检测来自多次散射、间接反射和周围背景的光会产生误差，尤其是在基于强度比的测量中。结构化激光照明平面成像（SLIPI）是一种成像技术，可显著减少此类问题的影响。在本研究中，SLIPI与双色激光诱导荧光比率测温法相结合，用于测量比色皿和空心锥喷雾中的水温。通过使用SLIPI消除不需要的背景干扰，我们观察到温度灵敏度有显著提高，喷雾中的温度梯度也更加明显。
