In this analysis, the Fourier coefficients for a sample are obtained using a discrete Fourier transform on the exposures. The analysis gives a generic function that encompasses the discrete Fourier transform or the Hadamard transform, depending on the specific conditions. Unlike the Hadamard transform, a well-known data acquisition method that is used only for conventional multichannel rotating-element ellipsometers with line arrays with specific readout-mode timing, this Fourier analysis is applicable to various line arrays with either nonoverlap or overlap readout-mode timing. To assess the effects of the novel Fourier analysis, the Fourier coefficients for a sample were measured with a custom-built rotating-polarizer ellipsometer, using this Fourier analysis with various numbers of scans, integration times, and rotational speeds of the polarizer.","is_dataset_classified":null,"base_score":2.4849066497880004,"endowment":2.4849066497880004,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21263472","pmcid":null,"openalex_id":"https://openalex.org/W1971280405","authors":[],"funders":[{"funder_name":"Center for Nanoscale Mechatronics & Manufacturing","grant_id":"2010K000207","title":null}],"total_grants":1,"fwci":0.2109,"citation_percentile":0.55125258,"influential_citations":0,"citation_trend":[{"year":2013,"count":1},{"year":2015,"count":2},{"year":2016,"count":1},{"year":2021,"count":3},{"year":2023,"count":1},{"year":2024,"count":2},{"year":2025,"count":1}],"oa_status":"closed","license":"https://doi.org/10.1364/OA_License_v1#VOR","oa_locations":[{"url":"https://www.osapublishing.org/viewmedia.cfm?URI=ol-36-2-118&seq=0","host_type":"publisher"},{"url":"https://doi.org/10.1364/ol.36.000118","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/21263472","host_type":"repository"}],"fields_of_study":["Optical Polarization and Ellipsometry","Color Science and Applications","Infrared Target Detection Methodologies"],"mesh_terms":[],"keywords":["Fourier transform","Fourier analysis","Discrete-time Fourier transform","Discrete Fourier transform (general)","Optics","Non-uniform discrete Fourier transform","Polarizer","Fourier series","Fractional Fourier transform","Discrete Fourier series","Physics","Mathematics","Mathematical analysis","Birefringence"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-03T01:46:21.934428Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
