Multiband Techniques of LED and UV Materials on Visualization of Needle Marks

Abstract:

Critical optical techniques on visualization and extraction about needle marks have been developed based on the material properties of the speedometer. It has developed the multi-band waves and special image processing to do multi-spectral analysis on the suspected needle marks locations. The in-depth discussion has been taken especially for UV fluorescence traces, and alternatives have been established for multi-spectral laser with the multi-wavelength LED light source. Issues have been solved such as size and power consumption to meet the needs of image acquisition and processing. It should choose the right light waves based on the optical properties for various materials of the needle and the gauge plate.
