Ultraviolet technology of detecting is playing a more and more important role in the field of civil application, especially
in the corona discharge detection, in modern society. Now the UV imaging detector is one of the most important
equipments in power equipment flaws detection. And the modern head-mounted displays (HMDs) have shown the
applications in the fields of military, industry production, medical treatment, entertainment, 3D visualization, education
and training. We applied the system of head-mounted displays to the UV image detection, and a novel type of
head-mounted displays is presented: the solar-blind UV head-mounted displays. And the structure is given. By the
solar-blind UV head-mounted displays, a real-time, isometric and visible image of the corona discharge is correctly
displayed upon the background scene where it exists. The user will see the visible image of the corona discharge on the
real scene rather than on a small screen. Then the user can easily find out the power equipment flaws and repair them.
Compared with the traditional UV imaging detector, the introducing of the HMDs simplifies the structure of the whole
system. The original visible spectrum optical system is replaced by the eye in the solar-blind UV head-mounted displays.
And the optical image fusion technology would be used rather than the digital image fusion system which is necessary in
traditional UV imaging detector. That means the visible spectrum optical system and digital image fusion system are not
necessary. This makes the whole system cheaper than the traditional UV imaging detector. Another advantage of the
solar-blind UV head-mounted displays is that the two hands of user will be free. So while observing the corona discharge
the user can do some things about it. Therefore the solar-blind UV head-mounted displays can make the corona discharge
expose itself to the user in a better way, and it will play an important role in corona detection in the future.
