Effect of Beam Size on Spatial Resolution of the PTR Systems
The definition of spatial resolution in the PTR (photothermal radiometry)system is given. The influence of incident beam size on spatial resolution is investigated.The theoretical anlysis and practical measurements show that focused incident beam improves the spatial resolution of the system greatly.
