Abstract
An imaging device includes a transparent prismatic element having two contiguous inlet surfaces separated by a ridge. A lens and an image sensor 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.
