This study introduces a new method for enhancing the accuracy of temperature measurements using thermochromic liquid crystal (TLC) particles. Traditionally, temperature has been determined by averaging the hue values from multiple TLC particles. Our approach, however, employs a single-camera setup combined with a mirror array to image particles from various angles simultaneously. Experimental results demonstrate a notable expansion in the measurable temperature range and a decrease in random error compared to traditional methods. Specifically, our technique extends the temperature range by 1.7 times and reduces the standard deviation of measurements by 75%.
