This holographic technique has been used before as a fluid velocimetry technique that allows measuring the three components of the fluid velocity in a plane. Since its performance is limited by the temporal and spatial coherence of the laser, we can take advantage of this and make IPDH with laminar illumination a means of obtaining these laser properties. The proposed method could be of interest for the optics community since it could be used for any type of light source, presenting some advantages by comparing it with other well-established techniques. It has been tested by using a high repetition rate laser commonly used in velocimetry and the results have been compared to those obtained with other standard techniques, verifying the well-functioning of the IPDH-based technique. info:eu-repo/grantAgreement/ES/DGA-FEDER/E44-23R info:eu-repo/grantAgreement/ES/MICINN/PID2020-113303GB-C22 info:eu-repo/grantAgreement/ES/UZ/UZ2020-CIE-04 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 5.0 2024 OPTICS 25 / 125 = 0.2 2024 Q1 T1 PHYSICS, APPLIED 49 / 187 = 0.262 2024 Q2 T1 1.0 2024 Atomic and Molecular Physics, and Optics 2024 Q1 Electronic, Optical and Magnetic Materials 2024 Q1 Electrical and Electronic Engineering 2024 Q1 9.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Torcal-Milla, Francisco J.
