一种DC-DC升压型开关电源的低压启动方案
Low-voltage Start Circuit of DC-DC Boost Switching Power Supply
摘要
Abstract
The characteristics of optical system in the daytime under the strong light condition are introduced. The spectrum filters can enhancement SNR measurement efficiently based on the model of optical detection for contrast, SNR and stellar in the daytime. The narrow-band filtering as superior spectrum filter Is proposed by contrasting various of filtering effect. Based on the model of optical detection, the influence of daytime detection from the optical system parameter through saw field, optical caliber, and focal distance is proposed.关键词
