Theoretical analysis of phase-resolved fluorescence emission from fingerprint samples

Basic theory for the detection and imaging of latent fingerprints using phase-resolved optical method is described. In this work, extraction of single fluorescence emission from fingerprint samples deposited on non-fluorescing substrate is described. Also, the significance of incorporating the heter...

Summary:Basic theory for the detection and imaging of latent fingerprints using phase-resolved optical method is described. In this work, extraction of single fluorescence emission from fingerprint samples deposited on non-fluorescing substrate is described. Also, the significance of incorporating the heterodyne concept in the signal-processing scheme in the formulated theoretical model is explained.
