Abstract

Abstract

To address the potential photobiological safety risks to humans during the use of iris scanners, two measurement methods, broadband radiance measurement and spectral radiance weighted measurement, were used to measure the radiation luminance of the retinal thermal hazards caused by micro-visual stimuli of iris scanners, and the results obtained by the two methods were analyzed and compared to derive the applicable measurement conditions for each of the two methods.
- photobiological safety,
- exposure limit,
- spectral radiance,
- spectral irradiance
