Abstract
A light communication system, a transmitter and a receiver are provided. The light communication system includes the transmitter and the receiver. The transmitter has a first processing unit and a light-emitting element. The first processing unit produces a transmission signal. The light-emitting element produces light to carry the transmission signal. The receiver has a first variable lens, a photosensitive element and a second processing unit. The first variable lens changes the propagation path of the light. The photosensitive element senses the light passed through the first variable lens to produce a receiving signal. The second processing unit controls the first variable lens based on the signal quality of the receiving signal to change the equivalent channel between the transmission signal and the receiving signal. Therefore, the transmission capability of the light communication system is enhanced.
