| Outline of Final Research Achievements |
The purpose of this study is to propose a new laser imaging method using laser refractive crystals and to establish its basic theory from the aspect of signal processing. By combining non-uniform observation and image interpolation techniques, a new signal processing approach was explored to achieve the required resolution in the required areas. During the research period, we clarified an appropriate observation method for situations where the entire image is unknown, and published the results in papers and other publications. The proposed method improved the image quality by an average of 1 dB in a metric called PSNR compared to the case of random observation.

本研究によって，単一センサを用いた撮像装置において不均一サンプリングと画像修復を組み合わせて使用した場合に，サンプリングの密度を動的に変化させる方法が最終的な修復画像に与える影響について明らかにした．この成果は必ずしも単一センサを用いた撮像装置のみに限らず，不均一サンプリングを活用する様々な観測装置において応用が可能であると考えられる．例えば磁気共鳴分光装置でも不均一サンプリングが用いられており，こうした化学計測の分野でも活用が期待される．
