Problems solved by technology

However, the above two detectors have the following problems: filters are required for work, which will inevitably limit the field of view; refrigeration is required for work, resulting in very large detector volume and power consumption

[0003] In ultraviolet detection, ultraviolet imaging has become the main and priority development direction. However, to realize omni-directional and large-scale detection and imaging based on traditional planar imaging devices, theoretically it is necessary to use a combination of four or six detectors, or use multi-degree-of-freedom rotation The combination of motor and single detector will undoubtedly increase the size and power consumption of the ultraviolet omnidirectional detection and imaging system
