Ever since Stiles and Holladay (1929), veiling glare (VG) in the human visual system has been known to hinder the visibility of subtle targets. In this work, we quantitatively study how veiling glare affects contrast detection tasks using a dual-layer high-dynamic-range (HDR) display and ...
ultrasonic cleaners for eyeglasses, and ultrasonic humidifiers. When employed as a sensing medium, ultrasonic waves can be used to detect transparent solid or liquid items or small objects in dark places as well as objects with low reflectance of radio waves. In recent years, ultrasonic sensors ...
