  • Patent number: 7576843
    Abstract: An optical device for biometric sensing by contact, comprising: an optical element (2) having a face (3) constituting a surface for apposition of a body part from which a biometric characteristic is to be sensed; a radiation source (6) for illuminating the face (3) of the optical element; and sensor means (9) for picking up the radiation coming from the face (3); the face (3) is coated in a thin layer defining a pattern and made of a material such that in association with the material constituting the optical element, the layer is transparent in the presence of radiation emitted by the radiation source (6) when a body part is placed on the face (3) and is significantly less transparent in the presence of external parasitic radiation (13) that is inclined relative to the face (3); whereby the image received by the sensor means can be distinguished depending on whether it is real or latent.
