Abstract:
1. A fingerprint imaging system configured to capture an image of a friction ridge pattern of a subject, the system comprising: a platen configured to engage the friction ridge pattern of the subject; an image capture device configured to electronically capture an image of the friction ridge pattern engaged with the platen; a radiation source configured to emit radiation towards the platen such that if the friction ridge is engaged with the platen a portion of the emitted radiation is reflected from areas on the platen at or near the interface between the friction ridge pattern and the platen, and travels to the image capture device along a primary optical path; one or more baffles disposed in the system between the platen and the image capture device, the one or more baffles being configured to block ambient radiation entering the system through the platen; one or more optical elements configured to fold the primary optical path around the one or more baffles.
