| 摘要 |
The present invention pertains to an optical shutter device comprising one or more photon absorbing materials that convert photons to heat in less than 1 nanosecond and one or more thermochromic materials that undergo an increase or decrease in optical density at one or more wavelengths when the thermochromic material is heated from 25 ~C to a temperature greater than 100 ~C in less than 1 nanosecond.
