Thus, for these reasons, it seems to be difficult for this method to analyze and visualize crystallographic information of oligocrystals. On the other hand, [PERSON] et al. developed a method which could analyze the crystal orientation along a neutron transmission direction from the full wavelength pattern of Bragg-dips [19]. This method was applied to position-dependent Bragg-dip neutron transmission spectra measured from an oligocrystal sample, and position-dependent crystal orientations could be derived over the sample. Because this method can analyze the crystal orientation without initial estimation, it can visualize crystal orientations of each grain whose crystal orientation is unknown. However, crystalline information except for crystal orientation cannot be obtained by this method. [PERSON] et al. developed a method which could visualize the misorientation in single crystals [20]. In this method, the bottom of Bragg-dip, namely the wavelength where the neutron transmission was the lowest, was considered as the wavelength where Bragg-dip appears. This method can map the wavelengths where Bragg-dips appear in real space. As a result, the misorientation in a single crystal can be visualized. However, this method is not the dip profile-fitting analysis. Therefore, other Bragg-dip profile information including various crystallographic information are not utilized. Thus, it is difficult for the conventional Bragg-dip analysis methods to visualize multiple detailed crystalline information position-dependently. Therefore, in this study, a new Bragg-dip neutron transmission spectrum analysis method was developed and applied to position-dependent oligocrystal evaluation. It is the single Bragg-dip profile-fitting analysis method. This method is applied to position-dependent Bragg-dip neutron transmission spectra. First of all, in the Bragg-dip transmission imaging experiment, neutron transmission spectra, including Bragg-dip, the profile of which reflects crystallographic information of a single crystal, are measured at each pixel of the time-of-flight (TOF) imaging detector for both wavelength analysis and imaging analysis of pulsed neutrons. Here, by the profile-fitting analysis of individual Bragg-dip in the neutron transmission spectrum, the wavelength, the width and the integrated intensity of Bragg-dip can be derived. Then, change in crystal orientation can be evaluated from change in the wavelength where Bragg-dip appears, mosaic spread angle can be evaluated from the width of Bragg-dip and change in thickness of a perfect crystal along the neutron transmission path can be evaluated from the integrated intensity of Bragg-dip. Because the method is a simple profile-fitting analysis, it is expected that the method can evaluate this detailed crystalline information position-dependently without difficult spectrum-fitting procedures. For this reason, in this study, we developed the single Bragg-dip profile-fitting analysis method. Then, this method was applied to experimental data of position-dependent Bragg-dip neutron transmission spectra measured from an oligocrystal material [19] to confirm the effectiveness of the new approach. As a result, a small change in crystal orientation inside a crystalline grain was detected in the real-space image. In addition, another crystalline grain and mosaic block in a crystalline grain which had not been observed by the previous data analysis method [19] could be observed in the real-space image. In this paper, the procedure of the single Bragg-dip profile-fitting analysis method and results of these new observations are reported. This paper is organized as follows. In Section 2, the outline of the wavelength-resolved neutron transmission imaging experiment using pulsed neutrons and the TOF method is described. In Section 3, the single Bragg-dip profile-fitting analysis method is explained. In Section 4, the imaging results of single Bragg-dip profile information are described, and newly evaluated crystalline information in crystalline grains is discussed.
