Photography involving the recording of events that occur too fast to be perceived by the human eye or recorded by conventional photographic techniques. See high-speed movie camera; high-speed...

high-speed radiography

A method of producing x-ray exposures as short as 0.03 µs; the primary application is in ballistic radiography.

high-speed shutter

A shutter actuated by means other than mechanical springs for timings on the order of nanoseconds. The shutter is used in the photography of rapid moving objects or events.

high-speed still camera

A still camera with a shutter capable of opening for a time as short as a fraction of a microsecond. An electronically operated Kerr cell often is employed.

high-vacuum tube

An electron tube whose electrical characteristics will not be affected by gaseous ionization because of its high degree of evacuation. Also known as a hard tube.

high-voltage electron microscope

An imaging device whose technology contributes three specific advantages: ability to study large solid specimens that exhibit behavior in bulk; conduction of in situ studies of radiation damage; and...

highlight

The portion of a reproduced image having the greatest luminance.

hill cloud lens

A fish-eye lens designed to photograph cloud formations over the entire visible sky.

himawari

A system of Japanese origin that utilizes Fresnel lenses and a fiber optic network to transmit sunlight to otherwise inaccessible areas.
