| Abstract(J) | CT半導体レーザ吸収法は２次元/３次元で温度・濃度を計測可能な手法であり、エンジンなどの燃焼場計測に応用されてきている。CT半導体レーザ吸収法では、各レーザ光路の吸収スペクトルから温度・濃度を再構成することが必要となり、再構成の高速化が望まれていた。本研究では、初期値データベースを用いた画像再構成の高速化評価結果とその適用例について述べる。 Translation |
| Abstract(E) | CT-tunable diode laser absorption spectroscopy(CT-TDLAS) is a method which can detect 2D/3D temperature and concentration distributions and has been applied to combustion analysis such as engines. It is necessary for CT-TDLAS to reconstruct 2D/3D images using absorption spectra of a set of laser paths, which takes computational time. The novel method of image reconstruction using a set of initial image database was developed and evaluated for the CT-TDLAS applications. |
