High-Resolution Single-Fiber Endoscope (image) Stanford School of Engineering Caption This is a schematic rendering of Kahn's rigid endoscope using a multimode optical fiber. Random patterns of light generated by a spatial light modulator pass through a fiber and illuminate a region near the fiber tip. Reflected power values are recorded and used to reconstruct an image. The arrows indicate the direction of light propagation.
