In Japan, two dimensional IRCCD cameras such as Nikon's LAIRD 3 have been sold by various manufacturers. In addition to the staring type IR cameras, there are mechanical scanning type IR cameras which are also receiving much attention in the market. The primary applications of the IR camera market have been night-time security surveillance, non-destructive testing and/or process control in the industrial environment. In such applications, infrared radiation emitted from the observed object is seen as heat. Thus, many IR cameras have been designed to maximize the amount of IR radiation collected from an observed object. One new application for the LAIRD3 camera is to observe the spectral signature of an object over a specific spectral band in order to determine the presence and location of a specific gas. This paper described the results of using this method to detect the presence and location of methane in an observed environment.
