Auto-Brightness Curve Model for a Night Vision Imaging System Compatible with White LED Integrally Illuminated Information Panels in Airplane Cockpits

摘要

This chapter explores the optimal brightness of a night vision imaging system compatible with green LED integrally illuminated information panels when pilots are reading in different ambient illuminance, in an attempt to build an auto-brightness curve model. A total of 285 fighter pilots took part in the experiment. The equipment used in the experiment included an LED panel and a system to simulate light environments. In every grade of the simulated brightness, pilots adjusted the minimum brightness, the optimal brightness, and the maximum brightness when they read the LED panel. According to the data, the auto-brightness curve models of the minimum brightness, optimal brightness, and maximum brightness were found for the 5th, 50th, and 95th percentile of the 285 pilots. The engineering applications for these models need to be verified by the users and might be revised according to the verification.
