Measurement and analysis techniques for the TPA-TCT of segmented devices are presented and discussed using a passive strip CMOS detector and a standard strip detector as an example. The influence of laser beam clipping and reflection is shown, and a method that allows to compensate these intensity-related effects for investigation of the electric field is introduced and successfully employed. Additionally, the mirror technique is introduced, which exploits reflection at a metallised back side to enable the measurement directly below a top metallisation while illuminating from the top.<\/jats:p>","DOI":"10.3390\/s23020962","type":"journal-article","created":{"date-parts":[[2023,1,16]],"date-time":"2023-01-16T05:30:07Z","timestamp":1673847007000},"page":"962","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Techniques for the Investigation of Segmented Sensors Using the Two Photon Absorption-Transient Current Technique"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4385-911X","authenticated-orcid":false,"given":"Sebastian","family":"Pape","sequence":"first","affiliation":[{"name":"European Organization for Nuclear Research (CERN), Esplanade des Particules 1, 1217 Meyrin, Switzerland"},{"name":"Department of Physics\u2014AG Kr\u00f6ninger, TU Dortmund University, 44227 Dortmund, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6555-0340","authenticated-orcid":false,"given":"Esteban","family":"Curr\u00e1s","sequence":"additional","affiliation":[{"name":"European Organization for Nuclear Research (CERN), Esplanade des Particules 1, 1217 Meyrin, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4824-1087","authenticated-orcid":false,"given":"Marcos","family":"Fern\u00e1ndez Garc\u00eda","sequence":"additional","affiliation":[{"name":"European Organization for Nuclear Research (CERN), Esplanade des Particules 1, 1217 Meyrin, Switzerland"},{"name":"Instituto de F\u00edsica de Cantabria (CSIC-UC), Avenida de los Castros, E-39005 Santander, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7013-9751","authenticated-orcid":false,"given":"Michael","family":"Moll","sequence":"additional","affiliation":[{"name":"European Organization for Nuclear Research (CERN), Esplanade des Particules 1, 1217 Meyrin, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,14]]},"reference":[{"key":"ref_1","unstructured":"Vila \u00c1lvarez, I., De Castro Manzano, P., Fern\u00e1ndez Garc\u00eda, M., Gonz\u00e1lez, J., Jaramillo Echevarr\u00eda, R., Moll, M., Montero, R., and Palomo Pinto, F.R.
