Dynamic Gain

A novel measurement system for the dynamic and static light sources is designed in this paper. The method of dynamic gain adjustment measurement is proposed according to the national standards on luminous intensity of dynamic and static light sources. The method is achieved by the way that microcontroller controlled the analog switches to switch automatically in different ranges and adjust the gain automatically depend on the light intensity. By designing the overall structure of the system and using the dynamic gain adjustment method, the range of dynamic measuring illumination can be from 0.001 up to 2000 . The illumination measurement to static light source and the dynamic light source in the peak luminous intensity are achieved via the combination of interval control and dynamic gain adjustment.

Illumination Measurement

The light is a most important natural resource for human to survive .Aiming at the shortcomings of the traditional light intensity measuring instrument ,a kind of high resolution illumination measurement system based on FPGA is designed ,which consists of special BH1750 light sensors and programmable logic gate array (FPGA) . A soft core Nios II is used as controller in the instrument, and BH1750 is put into use to acquire light signal .The testing results show that the design is feasible.
