With low-intensity light, the sub-latent image speck may rapidly revert to silver halide before sufficient photons have been absorbed to make it stable.
The reaction is accompanied by emission of low-intensity light at 428 nm.
Mr. Waldman invented not only the sunglasses, but also a set of low-intensity lights that project light from the blue-green spectrum.
It may have been a placebo, or that even low-intensity light had some biological effect.
For dawn simulation, a low-intensity light is timed to go on at a certain time in the morning before you wake up, and it gradually gets brighter.
As her eyes grew accustomed to the dark, she could see a double line of tiny low-intensity lights set into the floor leading away from the grid.
For passive mode-locking, ideally a saturable absorber will selectively absorb low-intensity light, and transmit light which is of sufficiently high intensity.
This uses a nonlinear optical process, the optical Kerr effect, which results in high-intensity light being focussed differently than low-intensity light.
Current systems began with a United States Air Force program which placed low-intensity blue lights on aircraft as counterillumination camouflage.
