Abstract
Provided is a hydrogen concentration measurement method including sequentially aligning a light source, a hydrogen detector including nanoparticles, and an image sensor, allowing the nanoparticles to react with hydrogen to provide hydrogenated nanoparticles, and substantially simultaneously passing light, emitted from the light source, through the hydrogen detector to allow the light to enter the image sensor, acquiring a speckle image from the light entering the image sensor, and detecting a hydrogen concentration from the speckle image.
