Prism- lens system design for fingerprint scanner.

Question

Accepted Answer

Prism-lens system design for fingerprint scanner involves using a prism to reflect light onto a lens and then onto a sensor.

The prism should be made of a material with high refractive index to ensure maximum reflection of light.
The lens should be chosen based on the desired field of view and resolution.
The sensor should be placed at the focal point of the lens to ensure sharp image capture.
The system should be designed to minimize distortion and aberrations.
Examples of prism-lens systems used in fingerprint scanners include the Total Internal Reflection (TIR) prism and the Dove prism.
