tristimulus colorimeter
->
colorimeter
A colorimeter is a device used to measure and quantify the color characteristics of an object or a light source. It provides objective and standardized color information, typically expressed in terms...
ultrasonic holography
->
acoustical holography
The optical reconstruction of image information contained in a sound field. First the diffraction pattern, formed by an object irradiated by ultrasonic rays, interferes with a mutually coherent...
ultrasonic
Ultrasonic refers to sound waves with frequencies higher than the upper audible limit of human hearing, typically above 20,000 Hz. These waves are termed ultrasonic because they are beyond the range...
uniform color space
A color space in which equal distances represent equal visually perceived color differences.
VAMP
visual-acoustic-magnetic pressure
VAR
visual aural range
VCASS
visually coupled airborne systems simulator
vergence
The angular relation between two light rays that originated at the same object point. Sometimes used to indicate the angle between the visual axes of the eyes.
VIDAT
visual data acquisition
videography
Videography refers to the process of capturing moving images and recording them in a digital format. It involves the use of video cameras, lighting equipment, and audio recording devices to create...
visibility meter
1. An instrument used to determine the visual range in an environment. 2. A type of photometer that artificially reduces an object's visibility to threshold limits and records the quantity of...
volumetric imaging
Volumetric imaging refers to the capture, visualization, and analysis of three-dimensional (3D) information from a volume of space. Unlike traditional two-dimensional (2D) imaging, which provides...
VRR
visual radio range
wavefront reconstruction
->
holography
Holography is a technique used to capture and reconstruct three-dimensional images using the principles of interference and diffraction of light. Unlike conventional photography, which records only...
whiteness measurement
The use of whiteness formulas to replace visual assessment.
