Investigating the Technical Superiority of Light-Based Biometrics through Optical Fingerprint Sensor Market Research
The technical foundation of optical fingerprint sensing lies in its simplicity and effectiveness. By utilizing a light source, typically LEDs, to illuminate the finger, the sensor captures the reflected light via a CCD or CMOS image sensor. The ridges of the finger reflect more light, while the valleys reflect less, creating a high-contrast image that serves as a unique biological signature....
