Circuit Detects Faint Flashes Against Bright Background
Abstract
Lightning detector is photocell-and-amplifier circuit detecting flashes of light against steady or slowly varying bright background. Measures luminous flux in scene under observation. Designed to detect lightning from spacecraft in orbit far above clouds. Also used on Earth to detect lightning from distance during day or night, or to detect other flashes of light in safety-related, scientific, industrial, and military applications.
