UV cameras
- Solar blind UV cameras sensitive in UV-B band
- Multi-sensor broadband imaging systems sensitive from shortwave UV-B band to SWIR
Solar blind UV cameras are imaging devices optimized to detect ultraviolet light of wavelengths below about 280nm. Such cameras are insensitive against sunlight due to negligible sensitivity to visible and long wavelength UV light. Solar blind UV cameras are used in a series of applications like corona detection, fire detection, combustion analysis, plasma research, testing UV lamps, etc. However, highly sensitive corona detection is the main mass application and these devices are of crucial importance in electric power industry. These imaging devices enable easy detection of degraded insulators of high voltage transmission lines, distributions and substations. They can see the emission of UV light when discharges occur at defect insulators. From design point of view solar blind UV cameras are actually bispectral imaging systems built by combining true UV camera with typical visible camera. These bispectral imaging system generate output image as overlay of typical visible image with UV image of analyzed UV source.
Three systems for testing SBUV cameras are offered:
-
UVIC test station for basic tests of SBUV cameras

UMET test system for expanded testing of SBUV cameras

USOL station for measurement of solar sensitivity of SBUV cameras

Multi-sensor broadband imaging systems sensitive
in spectral range from shortwave UV-B band to SWIR band
(from about 280nm to about 1700nm) are rare type of
imaging systems targeted mostly for space applications.
These imaging systems are typically built by combining
several cameras of different spectral bands to form a
single broadband imaging system. UVIR is a test system
optimized to enable expanded testing of these imaging
systems.
UVIR test system is in general a
variable target image projector that uses a series of
different targets to project their images into the direction
of the tested camera: UV camera, VIS camera, NIR camera,
SWIR camera. The tested camera generates copies of
the projected images. Quality of the images generated by
the camera is evaluated by human observers or by
software and its important characteristics of tested
camera are measured. The UVIR
test system in its basic version (UVIR-A) is a system
optimized to enable measurement of imaging parameters of
tested system (resolution, MRC, MTF). However, UVIR can
be also delivered in a more advanced version (UVIR-B)
capable to measure both imaging (resolution, MRC, MTF)
and radiometric parameters (sensitivity, noise
parameters, response function).
