Regulated Power Supply with High Power Factor for Hyperspectral Imaging Applications

Blog Article

Illumination is a crucial factor in hyperspectral imaging systems.In this respect, this work is focused on analyzing the influence of the light power source in acquiring hyperspectral images.To this end, a custom regulated power supply was designed and developed.This power supply was then integrated into a hyperspectral acquisition system, and several light stability measurements were conducted.

Finally, several parameters related to the stability of the light produced by those systems were extracted using image analysis techniques, and a statistical comparison among the different sauceland power supplies was performed.Two commercial power supplies were also analyzed under the same experimental conditions and compared with the proposed power supply.The hyperspectral measurements were conducted using light transmission and reflectance.The results indicate that the proposed power supply performs better than or at least as well as commercial power supplies in terms of light stability.

Additionally, this study shows the grace in la cactus jeans impact of power supply design on the stability and quality of hyperspectral illumination, especially concerning the signal-to-noise ratio (SNR) across different spectral bands.It is shown that optimizing the design of the power supply could improve light stability in hyperspectral imaging applications.
