About the technology
Beam Profile Analysis is an active optical measurement method patented by trinamiX. It serves as the technological foundation for secure Face Authentication, skin health checks, and the monitoring of vital signs.
Beam Profile Analysis is based on algorithms that evaluate individual beam profiles. In this process, individual light points are projected onto an object to be analyzed, and their reflections are captured by an infrared camera. The algorithms can derive information about the object based on the specific beam profile. This includes details such as the material of the object, its distance, surface characteristics, and vital signs for humans.

Beam Profile Analysis for Biometric Imaging Applications
In the context of liveness check for secure Face Authentication, Beam Profile Analysis focuses on recognizing human skin and distinguishing it from other surface materials. This mechanism, known as liveness check, ensures that during the authentication process, a detected face is indeed that of a human being and not merely a realistic mask or a photo of that person.
In addition, Beam Profile Analysis provides information about the distance of the object thus enabling a 3D map of the object.
Regarding skin health, the technology can be utilized to analyse skin texture, which can provide insights into skin moisture levels.
For monitoring vital signs, it captures changes in light reflection caused by the pulsating blood flow, enabling, for instance, the contactless measurement of pulse rate.
