概要
- 論文の詳細を見る
An acousto-optic laser deflector was applied to laser interferometric measurement of impulse discharges in air as a high-speed shutter. Laser interference fringes were obtained at exposure times of about 1 μs. The deflector was also used for time-resolved imaging of laser interference fringes by using a sequence of high frequency signals with different frequencies to deflect the laser beam to different angles at different times, allowing multiple interference images to be captured on a single video frame. Changes in laser interference fringes due to an impulse discharge in air showed electron densities of about 2x1024 m-3 and perturbation in the neutral density expanding at speeds of about 103 m/s.
