Problems solved by technology

[0002] Ultraviolet image digital photography and camera devices are used in the collection and extraction of residual fingerprints, palm prints, scratches and other residual traces in public security criminal investigations, and in power transmission and transformation systems for corona discharge detection and fire monitoring and other ultraviolet image signals. and analysis are widely used, but at present, the ultraviolet image digital photography and camera devices used in these fields generally have the disadvantages of complex structure, heavy, difficult operation, inconvenient use, unstable work, and low work efficiency.

For example, CN2610846 discloses a kind of ultraviolet image viewer that is used to show traces such as residual fingerprints, palm prints, sweat stains, and blood stains. Due to structural reasons, it still has the disadvantages of inconvenient use and low work efficiency.

However, most of the existing ultraviolet camera devices for corona discharge detection in power transmission and transformation systems are complex in structure and expensive.
