摘要：
利用相敏检测法测量了激光束在调制电场中的偏转，并给出了光子电荷的上限。得到了$10^{-14}e$的上限。该实验涉及一些现代精密测量中常见的实验技术，适合物理科学的高年级本科生和研究生作为实验室练习。
英文摘要：
The deflection of a laser beam traveling through a modulated electric field is measured using phase-sensitive detection to place an upper bound on photon charge. An upper limit of $10^{-14}e$ is obtained. The experiment involves a number of experimental techniques that are commonly encountered in modern precision measurements and is suitable for both advanced undergraduate and beginning graduate students in physical science as a laboratory exercise.
