Abstract
An imaging apparatus suitable for capturing a image of one or more of a user's facial features is disclosed. The apparatus includes a spherical cold mirror which presents a concave surface to the user and is disposed between the user and the camera. The user is able to conclude that he is close enough to the camera for successful image capture when the reflection he sees in the mirror is the right way up. In a preferred embodiment, markings are provided on the front surface of the mirror to aid the user in placing his eye within a predetermined range of distances from the camera. The imaging apparatus is suitable for use in iris recognition apparatuses and provides a relatively inexpensive alternative to known apparatuses.
