Abstract

A biometric device includes an illuminating unit and an imaging module. The imaging module includes an optical angular selective structure and a sensing layer. The light selecting structure includes amicro lens array, a refractive layer and a light shielding layer. The refractive layer is disposed between the micro lens array and the light shielding layer. The micro lens array includes a plurality of lens unit units, and the light shielding layer has a plurality of light passing portions. The sensing layer defines multiple sensing regions which are spaced apart from each other. The light shielding layer is disposed between the refractive layer and the sensing layer. The sensing regions correspond to the light passing portions, respectively. An optical angular selective distance is definedbetween the light shielding layer and the sensing layer.

Description

technical field [0001] The invention relates to a biometric identification device, in particular to a thinned biometric identification device. Background technique [0002] Biometrics (recognition) technology refers to the use of the physiological or behavioral characteristics of the human body to achieve the purpose of identification and authentication authorization. The physiological characteristics of the human body include fingerprints, palm prints, vein distribution, iris, retina and facial features. Nowadays, biometric technology has been applied in digital assistants, smart phones, notebook computers, financial cards, electronic wallets and customs clearance, etc., where there is a high demand for information privacy and personal safety. [0003] Generally speaking, widely used biometric technologies include fingerprint recognition and vein recognition. In order to focus the light reflected by fingers or veins onto the photoreceptor in existing fingerprint recognitio...
