<p>A compact handheld imaging apparatus (700) which can be used to capture high-quality iris images for identification of a person. The handheld iris imager is non-invasive and non-contacting and comprises a camera (105), a cold mirror (120), a lens (110), and an illuminator (130). The imager has sensors and indicators (555, 556, 557, 560) which assist a user in aligning and focusing the device. The imager also automatically captures the image when proper positioning is achieved. A template of the image is then compared to a database of previously stored templates of images to identify the person. The imager is integrated into a telecommunications device as a security module. The telecommunications device cannot be unlocked and used unless a user has been identified and authorized by the imager.</p> |
