| description | The paper presents technical description of pulse LED backlight. This system is implemented in machine vision systems designed for high-speed processes control. Pulse projectors managed on the basis of starting time and duration of the pulse. The system provides control of electrical parameters of projectors, such as input voltage and current of the LED array, which are measured during backlight pulse operate time. This information gives an indirect measurement of the LED arrays' state. The design of the system and implementation example are given. |
