Problems solved by technology
Photodiodes are relatively large in size, and it is difficult to expand the number on the focal plane of the optical lens
In addition, although the time resolution of this high-speed optical speed measuring device meets the observation requirements, it mainly focuses on the development speed of the leader in the vertical direction, and cannot simultaneously observe the development speed of the leader in the horizontal direction.
[0005] Therefore, the problems existing in the prior art are: the sub-microsecond optical observation device cannot observe the two-dimensional development speed of the transient light process, it is inconvenient to expand, and the accuracy is not high

Description
technical field [0001] The invention belongs to the technical field of optical observation equipment, in particular to a sub-microsecond two-dimensional optical observation device capable of simultaneously observing the intensity, rise time and two-dimensional development speed of a transient light process, which is easy to expand and has high observation accuracy. Background technique [0002] For the rational design of lightning protection system, it is very important to correctly understand the pilot connection process, but the randomness of lightning development makes the pilot connection process complex and changeable, so the current understanding of the connection process is still relatively lacking. Compared with electrical means, optical observation can clearly and intuitively present the detailed characteristics of the leader's channel shape, stepping speed, and thunderstorm intensity. [0003] Due to the short duration and small scale of the uplink leader, it is no...
