Publication number: 20230146740Abstract: A spectrometer capable of providing information, to a measurer, necessary for determining whether a sample set to the spectrometer is a sample expected by the measurer or not before a main measurement includes a data processor and a display. The data processor calculates a preliminary spectral information of the sample based on at least n of a latest detected signal and a BKG information retained in advance, calculates and updates the preliminary spectral information based on at least n of the latest detected signal and the BKG information again, and repeats these calculations and updates. The display shows the preliminary spectral information that is calculated and updated in the preview display. The data processor starts integration of N (N>n) of the detected signal during a preview display of the preliminary spectral information, and acquires a spectral information of the sample.Type: ApplicationFiled: November 4, 2022Publication date: May 11, 2023Applicant: JASCO CORPORATIONInventors: Kenichi AKAO, Yuji HIGUCHI, Tsubasa ASATSUMA

Patent number: 7515769Abstract: It is an object of the present invention to provide a mapping-data analyzing method that can display a map in which sufficient information is extracted from the spectra of obtained mapping data to enable objective analysis. The mapping-data analyzing method of the present invention is used for analyzing mapping data obtained by measuring, with a spectrometer apparatus, spectra at a plurality of points on a specimen surface. The method comprises a principal-component calculating step and a grouped-map display step. In the principal-component calculating step, spectral data obtained at each point on the specimen surface is defined as an individual sample and principal component analysis, in which values at a plurality of wave numbers of each spectral data set serve as variables, is performed to calculate the scores of a plurality of principal components for each individual sample.Type: GrantFiled: October 24, 2005Date of Patent: April 7, 2009Assignee: Jasco CorporationInventors: Kenichi Akao, Toshiyuki Nagoshi
