Multi-spectral imager

Abstract

This poster highlights the design and development of a camera which combines ultraviolet, infrared and visual imaging techniques for advanced diagnostic inspections, and also shows some evaluations carried out to demonstrate the operability and sensitivity of the imager. The wavelengths of the electromagnetic spectrum are divided into different categories, such as the x-ray domain for short wavelengths with powerful penetrable photons, the visible spectrum where human beings can observe objects and the long length radio waves for communication purposes. The multi-spectral imager explores the ultraviolet wavelengths between 200nm to 280 nm for visualising high voltage corona discharges, the visible wavelengths of 400 nm (dark blue) to 780 nm (red) for correlating UV and IR to the visual spectrum and the heat wave lengths of 8 μm to 12 μm for locating hot spots
