IMAGING DEVICE HAVING A PRISMATIC ELEMENT

摘要

The invention relates to an imaging device (100) including a transparent prismatic element (1) having two contiguous inlet surfaces (E1, E2) separated by a ridge (A). A lens (2) and an image sensor (3) make it possible to acquire images, each including a reproduction of a first pattern located against one of the inlet surfaces, and a reproduction of a second imaged pattern through the other inlet surface. Such a device can be used in a biometric detection apparatus for detecting both a skin print and the vein distribution of a user. The device can also be used in a reading terminal capable of detecting a skin print and a machine-readable tape.
