Here, we propose to relieve the restriction by combining a diffraction grating and a low-cost diffractive element, which enables wide-angle two-dimensional beam steering. An FoV far beyond the reach of other spectral scan methods can be achieved. Several diffractive elements samples are fabricated to demonstrate spectrally scanning field of views of$7.7^{\\circ } \\times 10^{\\circ }$and$7.7^{\\circ } \\times 29^{\\circ }$from an 100-nm wavelength tuning range. Also, to show the potential to further extend the spectral scan range, blazed diffractive elements are fabricated with high diffraction efficiency, which corresponds to a spectral scan range up to 40.3°. Based on the structure, a solid-state coherent LiDAR system is built. Three-dimensional imaging with mm-level range resolution is demonstrated.","is_dataset_classified":null,"base_score":1.9459101490553132,"endowment":1.9459101490553132,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21097893","pmcid":null,"openalex_id":"https://openalex.org/W4285283688","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"61875104","title":null},{"funder_name":"Shenzhen Technology and Innovation Council","grant_id":"WDZC20200820160650001","title":null},{"funder_name":"Shenzhen Technology and Innovation Council","grant_id":"JCYJ20180507183815699","title":null}],"total_grants":3,"fwci":0.3577,"citation_percentile":0.47692518,"influential_citations":0,"citation_trend":[{"year":2022,"count":1},{"year":2023,"count":1},{"year":2024,"count":2},{"year":2025,"count":1},{"year":2026,"count":1}],"oa_status":"closed","license":"https://doi.org/10.15223/policy-029","oa_locations":[{"url":"http://xplorestaging.ieee.org/ielx7/68/9849088/09826837.pdf?arnumber=9826837","host_type":"publisher"},{"url":"https://doi.org/10.1109/lpt.2022.3190072","host_type":"journal"}],"fields_of_study":["Optical Coherence Tomography Applications","Advanced Optical Sensing Technologies","Optical measurement and interference techniques"],"mesh_terms":[],"keywords":["Beam steering","Optics","Spectral resolution","Lidar","Spectrometer","Range (aeronautics)","Diffraction grating","Physics","Diffraction efficiency","Wavelength","Diffraction","Grating","Field of view","Materials science","Beam (structure)","Spectral line"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-18T21:11:10.991283Z","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":[]}
