The recording geometry and index modulation of the hologram were optimised to improve accuracy for this specific application. The sensor was subjected to tests using various analytes, and it exhibited sensitivity to acetic acid and ethanol. The measurements revealed a correlation between the concentration of the analyte in contact with the sensor\u2019s surface and the resulting wavelength shift of the diffracted light. The minimum detectable concentrations were determined to be above 0.09 mol\/dm3 for acetic acid and 5% (v\/v) for ethanol. Notably, the sensors demonstrated a rapid response time. Given that ethanol serves as a base for alcoholic beverages, and acetic acid is commonly found in commercial vinegar, these sensors hold promise for applications in food quality control.<\/jats:p>","DOI":"10.3390\/s23218776","type":"journal-article","created":{"date-parts":[[2023,10,27]],"date-time":"2023-10-27T11:50:18Z","timestamp":1698407418000},"page":"8776","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Holographic Sensor Based on Bayfol HX200 Commercial Photopolymer for Ethanol and Acetic Acid Detection"],"prefix":"10.3390","volume":"23","author":[{"given":"Ioana-Adriana","family":"Pot\u0103rniche","sequence":"first","affiliation":[{"name":"Basis of Electronics Department, Faculty of Electronics, Telecommunication and Information Technology, University of Cluj-Napoca, 400114 Cluj-Napoca, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6899-1005","authenticated-orcid":false,"given":"Julia","family":"Mar\u00edn-S\u00e1ez","sequence":"additional","affiliation":[{"name":"Applied Physics Department, Escuela Polit\u00e9cnica Superior, University of Zaragoza, Crta. de Cuarte s\/n, 22071 Huesca, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3299-253X","authenticated-orcid":false,"given":"M.
