摘要:
A fingerprint imaging system configured to capture an image of a friction ridge pattern of a subject (e.g., a fingerprint, a palm print, a hand print, a footprint, etc.). The system may include one or more components that reduce the impact of ambient light on the performance of the system. In some implementations, the system may reduce the impact of ambient light without requiring additional power (e.g., to generate an increased amount of radiation) and without including “external” hoods and/or covers designed to block ambient light prior to the ambient light entering system. Instead, the system may reduce the impact of ambient light on performance by blocking ambient light internally within the system along an optical path of radiation used to electronically capture an image of the friction ridge pattern.
