Guidelines for Optimizing Optical System Design for Laser Speckle Authentication

Abstract

This study presents design-rule compliant optical system guidelines for laser speckle authentication, clarifying key parameter constraints. We reveal the relationship between sampling and speckle size, and experimentally show enhanced robustness against displacement. Quantitive analysis using false acceptance and false rejectance rates confirms reliable performance of our design-rule compliant system.
