光学搜寻地外文明计划已经40年了。然而，只是在世纪的最后几年，在中断了25年之后，光学搜索才在SETI社区中重新获得尊重。美国光学SETI研究的四分之一个世纪的延迟是由于历史事故，而不是因为缺乏任何使能技术。本文介绍了过去，现在和未来的光学SETI计划。重点放在检测快速，脉冲引起注意的激光信标信号，而不是单色，连续波信标。商业探测设备，可用于任何类型的OSETI的一些例子。
The Optical Search for Extraterrestrial Intelligence is now 40 years old. However, it was only during the closing years of the 20th Century, after a 25-year hiatus, that the optical search has regained respectability in the SETI community at large. The quarter-of-a-century delay in American Optical SETI research was due to a historical accident and not for the lack of any enabling technology. This review paper describes aspects of past, present and future Optical SETI programs. Emphasis is placed on detecting fast, pulsed attention-getting laser beacon signals rather than monochromatic, continuous wave beacons. Some examples of commercial detection equipment that may be employed for either type of OSETI are given.
