antigen
An antigen is any substance that is capable of triggering an immune response in an organism. Antigens are typically proteins or large polysaccharides, although other types of molecules can also act...
backstreaming
The term used in reference to vacuum systems using oil and diffusion pumps, describes the migration of pump fluids and their decomposition products into the vacuum chamber.
chirped-pulse amplification
Chirped pulse amplification (CPA) is a technique used in laser physics to amplify ultrashort laser pulses to high energies without causing damage to the amplifying medium. The method was first...
circle of confusion
The image of a point source that appears as a circle of finite diameter because of defocusing or the aberrations inherent in an optical system.
computational imaging
Computational imaging refers to the use of computational techniques, algorithms, and hardware to enhance or enable imaging capabilities beyond what traditional optical systems can achieve. It...
diffusion disk
An embossed or marked disk, constructed out of a transparent material and used with a camera system to soften an image.
fiber joints
Fiber joints, also known as fiber optic splices, refer to the connection points where two optical fibers are permanently joined together to form a continuous optical transmission path. These joints...
fiber optic cable assembly
A fiber optic cable assembly refers to a complete unit consisting of optical fibers, connectors, protective jackets, and other components that are assembled together to facilitate the transmission of...
GRIN lens
A GRIN (gradient index) lens is a type of optical lens that utilizes a gradient in refractive index across its volume rather than having a uniform refractive index like conventional lenses. This...
image quality
A measure of the closeness with which an optical image is capable of resembling the original object. The factors that affect image quality are lens aberrations, diffraction, dirt and stray light...
inverse bremsstrahlung
Collisional absorption of energy that occurs in inertial confinement fusion systems when hydrodynamic expansion of the plasma causes an electron passing through the field of an ion to absorb...
Ioffee bar
A fusion system conductor capable of carrying current in opposite directions in alternating time phases.
microenvironmental control system
Equipment that supports microscopic live-cell imaging by managing the gas, media perfusion, temperature and other factors to which a sample is exposed. While reducing the negative impacts these...
multimodal vision-language models
Multimodal vision-language models (MVLMs) are advanced AI systems designed to understand and process information that combines both visual and textual data. These models are capable of interpreting...
optical parametric chriped-pulse amplification
Optical parametric chirped-pulse amplification (OPCPA) is an advanced technique used in ultrafast laser systems to amplify optical pulses to extremely high intensities while maintaining their short...
otoscope
An otoscope is a medical device used by healthcare professionals, particularly ear, nose, and throat (ENT) specialists, primary care physicians, and pediatricians, to examine the ear canal and...
