Abstract

In this letter, an integrated sensing and lighting (ISAL) system is proposed utilizing commercial red, green, and blue light-emitting diodes (RGB-LEDs), where the B-LED and G-LED operate continuously in the direct-current mode for lighting, while the R-LED alternates between the lighting and sensing modes in a time-division manner. An optimization problem regarding the optical powers and sensing duration is formulated to maximize the detection probability under the lighting constraints. Based on the analysis of the optimality conditions, the original optimization problem involving four parameters is simplified as an optimization problem with respect to a single parameter. The optimal solution can be readily obtained by utilizing the unimodal property of the objective function. Experimental results verify that the detection probability of the optimized scheme is significantly increased compared to the unoptimized schemes.

基于rgb - led的传感与照明集成系统的优化

在这封信中，提出了一个集成传感和照明（ISAL）系统，利用商业红、绿、蓝发光二极管（rgb - led），其中B-LED和G-LED在直流模式下连续工作，而R-LED在照明和传感模式之间以时分方式交替。在光照约束下，提出了光功率和传感时间的优化问题，使检测概率最大化。在分析最优性条件的基础上，将原来的四参数优化问题简化为单参数优化问题。利用目标函数的单峰性，可以很容易地得到最优解。实验结果表明，与未优化方案相比，优化方案的检测概率显著提高。
