The Tiny Giant: Fiber Optic Tapers Revolutionizing Compact Imaging
1. Fiber Optic Taper (FOT)
The image which is pressed against one end of fiber optic inverter (FOI) is resolved to the correspondent pixels by millions of fibers, and the pixel information is transmitted to the other end of the FOT one by one through the total reflection of light. The pixels are enlarged or reduced with the fiber diameter and are imaged at the output end according to the original arrangement.
2. Working Principle
Light Coupling Enhancement: The large end of the FOT matches the optical system's exit pupil, while the small end aligns with the CMOS sensor, minimizing energy loss.
Image Plane Adaptation: The taper scales the image without distortion when the optical system's image size mismatches the sensor, avoiding field cropping or resolution reduction.
High Transmittance: High-quality fibers (e.g., fused silica) reduce scattering.
3. Applications
Scientific Imaging: Coupling MCPs to CMOS in particle detectors; astronomy focal plane reduction.
Medical Endoscopy: Miniaturized imaging for laparoscopes with 1–2mm tapers.
Industrial X-ray: Scintillator-to-CMOS coupling in PCB/CT inspection.
