Instead of using a costly laser, he found an engineer to design a bundle of light-emitting diodes, which in 1993 were just beginning to be used in taillights in cars.
Hopefully we look over the darkness of the sea, which is as smooth as a mirror: In various places there emerges all around a flashlike bundle of light beams, like thousands of sparks, that form true bundles of fire and of other bright lighting spots, as if they are surrounded by mirrored stars.
An MI-150 fiber optic illuminator (Edmund Optics Inc., Barrington, NJ, USA) with a 150-W EKE halogen light bulb produced a high intensity bundle of light (450 to 800 nm), covering our wavelength range of interest for fluorescence imaging.
"My mom would say I'm a bundle of sunshine, that I light up a room," she said.
We designed a 64-channel (a bundle of 16 tetrodes), ultra-light (<2 g) and movable recording microdrive (Figure S1) similar to that described previously [37].
A 32-channel (a bundle of 8 tetrodes), ultra-light (<1 g), movable (screw-driven) electrode array was constructed similar to that described previously [41].
A 32-channel (a bundle of 8 tetrodes), ultra-light (weight <1 g), movable (screw-driven) electrode array was constructed similar to that described previously [49].
The reflected light from the sensing surface was collected by a bundle of optical detection fibers in the light probe.
But Mr. Prom bravely threw on his parka and lighted a bundle of birch bark to start a fire.
During a traditional smudging ceremony, a shaman, or medicine man, lights a bundle of herbs (usually sage, sweetgrass, or cedar) and uses his hand or feathers to fan the smoldering smoke over the person who needs a hit of the good stuff.
The size of an aperture is limited by the size of the mount holding the optical component, or the size of the diaphragm placed in the bundle of light rays.
