Abstract
A corona detection device includes a bandpass filter having a primary passband that includes at least wavelengths in the range of about 250 nm to about 400 nm and a secondary passband that includes wavelengths in the range of about 675 nm to about 850 nm. The corona detection device also includes an image intensifier in optical communication with the bandpass filter. The image intensifier is configured to generate an image based on radiation passed through the primary passband and the secondary passband of the bandpass filter.
Claims19
A corona detection device, comprising:
- a bandpass filter having a primary passband that includes wavelengths in a range of about 250 nm to about 400 nm and a secondary passband that includes wavelengths in a range of about 675 nm to about 850 nm;
- and
- an image intensifier in optical communication with the bandpass filter and configured to generate an image based on radiation passed through the primary passband and the secondary passband of the bandpass filter.
A corona detection device, comprising:
- a body;
- a hand grip attached to the body;
- and
- an optical assembly mechanically coupled to the body, wherein the optical assembly includes:
- a bandpass filter having a primary passband that includes wavelengths in a range of about 250 nm to about 400 nm and a secondary passband that includes wavelengths in a range of about 675 nm to about 850 nm;
- an image intensifier in optical communication with the bandpass filter and configured to generate an image based on radiation passed through the primary passband and the secondary passband of the bandpass filter;
- and
- a lens disposed along an optical path including the bandpass filter and the image intensifier.
A method of detecting corona emitted from an object, including:
- collecting radiation emitted or reflected by the object;
- passing the radiation through a bandpass filter having a primary passband that includes wavelengths in a range of about 250 nm to about 400 nm and a secondary passband that includes wavelengths in a range of about 675 nm to about 850 nm to provide filtered radiation;
- providing the filtered radiation to an image intensifier in optical communication with the bandpass filter;
- generating an image at the image intensifier based on the filtered radiation;
- and
- inspecting the image generated by the image intensifier.
