Using a planar-cryotarget system with the cooling power provided by a Gifford–McMahon cryocooler, the deuterium vapor is condensed to form liquid in a cylinder target cell. The liquefaction processes of deuterium are examined by the Mach–Zehnder interference and infrared spectra. The infrared-absorption spectra of deuterium show a strong absorption peak around 3040 nm at 19 K. The thickness distribution of the condensed deuterium in the target cell is determined from Mach–Zehnder interference images by developing a new mathematical treatment method in combination with the digital-image processing technique.
