A method for monitoring hydrogen gas and a hydrogen flame characterized in that the object light having a wavelength of about 309 nm resulting from two laser beams entering a space to be monitored is focused to form an electronic image, and the electronic image is amplified and converted back into an optical image, thereby creating an image showing a spatial intensity of a specific wavelength. A device for monitoring hydrogen gas and a hydrogen flame characterized by comprising two or more laser light source, focusing means for focusing the object light having a wavelength of about 309 nm resulting from laser beams in a space to be monitored, image-forming means for converting the object light into an electronic image, amplifying the electronic image, and converting it back into an optical image, and an imaging means for creating an image of spatial intensity distribution of a specific wavelength.
