N2 - In this study,a laser headlight electric control system was developed and implemented to measure and compare the electro-optic characteristics of the laser diodes. To observe different temperatures influenced the optical output power (OOP) and electrical power variations of the laser diodes,which was placed in an ambient temperature-testing chamber,and then the electro-optic characteristics of the laser diodes could be measured to calculate the electro-optic translation efficiencies. In conclusion,the different OOPs and electro-optic translation efficiencies at different temperatures could be obtained when OOP adjustment was performed by continuous constant-current and pulse-duty-cycle modulation technologies.
