Following explanation to the terms that you should know about Fiber Optic Plates.

1.Fiber Diameter (Pitch)

Diameter of a fiber strand / Distance between fiber centering

2.Numerical Aperture

Capability of light gathering of fiber optic components.


The measure of how closely lines can be resolved in one milimeter


Extra Mural Absorption(EMA) are small black fibers that inserted between 2 fiber strands. Which will absorb stray light between fibers.


The transmitting part of the fiber optic wave guide. (Core usually has higher refraction index than cladding)


The cover outside core, cladding has a lower index of refraction than core.

7.Packing Fraction

Ratio of Core area to Total area, this will shows the light transmission efficiency of the component.


Comparison between Output light intensity and Input Light Intensity

10.Optical Crosstalk

The light escape from one fiber strand and get into another fiber.


Blemishes are the area where transmission is reduced. Blemish is caused by contaminants along in the fibers.


Chicken wire appear likes a black line on the components. The result of chicken wire is due to mal-control of temperature or pressure during the procedure.

13.Coefficient Thermal Expansion

CTE defined as the changing of dimension when the fiber components exposed to changing temperature environment

14.Shear Distortion

Shear distortion is cause by the misalignment of fiber during fusion process.

15.Gross Distortion

Gross Distortion is cause by in-proper Temperature/Pressure and Material input procedure.

Fiber Optic Taper coupling to CCD/CMOS/OLED

Fiber Optic Taper could be used in the device of Medical Radiography, such as Dental and Mammography. For example, in the Mammography, when exposed to X-Ray, Scintillator will absorb X-Ray and transfer them into visible light. Then pass through Fiber Optic Taper for minify the image signal. At last, Image sensor will receive the minified image signal and turns it into numerical signal. This type of system can greatly reduce exposure of X-ray on patients, which could protect personnel in the long run.

In the Dental X-Ray detection, a round or rectangle fiber optic taper is used to minify the image and connect to CCD or CMOS. The whole system is integrated into a plastic device, which could at least cover an image area of 1-2 teeth.

The technique of coupling Fiber optic taper to CCD is the key technique of Developing ICCD image sensor. Compared with traditional lens imaging system, the FOT x CCD system has a higher coupling efficiency and it can greatly minimize the size and weight of camera.

FOT (fiber optic taper) can be used as a coupler to CCD chips.
Following their advantages in the applications:

  • Protection CCD/CMOS from X-Ray damage.
  • Magnify (Minify) image direct coupling to other device.
  • Suitable for a compact optical design
  • More efficient than traditional lens imaging system.
    (Low distortion, High image quality)
  • Combination of FOT array to accept a large viewing area
  • Notice during CCD bonding design
