Application of fiber optic plate in the fingerprint sensors
Is a new miniature optical fingerprint sensor of low cost and high resolution your ultimate goal?
Are you still worried about the plate material of high resolution?
Guangzhou Honsun Opto-electronic Co.,Ltd will completely solve the problem for you!
Introduction
In October 2014, HIS, a marketing research company, predicted that the global market of fingerprint sensor will increase almost four times to nearly $1.7 billion by 2020. Most of the growth will come from Asia, especially China. In 2013, the size of global market for fingerprint sensor used for mobile phones and tablets was only $500 million. We have reasons to believe that so many competitors are rubbing their hands and getting ready to move into this growing market. In fingerprint sensor, how to make choice between optical sensor and capacitance sensor? How can it be miniature, low-cost and with high resolution? The use of fiber optical plate will solve this problem for you!
The Application and Technical Advantages of Fiber Optic Plate in Fingerprint Identification Technology
The principle&structure of using fiber optic plate to gather the fingerprint module
As gathering window component,the fiber optic plate can transmit fingerprint image with 1:1 high definition and high fidelity. The image transmission effect is just like a finger directly pressing on the image sensor directly.
Contrast with the common technologies of fingerprint acquisition.

The Structural Principle of Fiber Optic Plate
Fiber Optic Plate
Fiber Optic Plate (hereinafter referred to FOP) is a glass product composed of many optical fibers by parallel arranging, screen pressing and cold working. It can transmit the optical image from one side to the other with high resolution in zero optical path (zero thickness) , as shown in the pictures.
The resolution of general fiber optic plate can be 4200 ppi. Products with the resolution ≤6000ppi can be customized according to customer's requirements. The dimension can also be customized according to customer's request.
