From: Image Transport Through Meter-Long Randomly Disordered Silica-Air Optical Fiber
Images of numbers, line elements and the corresponding intensity profiles of the line elements after transport through 90 cm of GARF(1). (a1–a3) and (c1–c3) are the results obtained keeping the GARF(1) straight; while (b1–b3) and (d1–d3) are obtained using the same 90 cm long GARF(1) sample with a 180 degree turn (20 cm bending radius). The illumination wavelength for (a1–a3) and (b1–b3) is 405 nm, and the wavelength for (c1–c3) and (d1–d3) is 635 nm. The number “4” belongs to group 3 on the resolution target. The line elements in (a2) and (b2) belong to group 4 number 5 on the resolution test target. The line elements in (c2) and (d2) belong to group 4 number 3. The visibility values are 0.35 for (a3), 0.33 for (b3), 0.26 for (c3), and 0.31 for (d3), respectively.
