Abstract

With the view to the requirement of field experiments in Low-Light-Level (LLL) situation, the handheld digital illuminometer is designed based on LLL image intensifier, which is convenient to operate, smaller in size and weight. According to the linear relationship between screen-end current in image intensifier and illuminometer, the screen-end current is designed as signal input. It is converted from analog signals by A/D conversion, and displayed by display unit. Compare with the test data from standard illuminometer, modify MCU (Micro-programmed Control Unit) software. The illuminometer modified can measure the illumination range 10^-3 lux to 10^-2 lux, meet the demand of measuring in field experiments fundamentally.
