An image conduit is an optical device that can transfer an image plane spatially. It can use fiber optics.
It uses a bundle of fibers. Each fiber has TIR.
They are also called image guides, leached image bundles, and leached fiber bundles.
It is also known as a fiber optic image bundle.[1]
They can be rigid or flexible. If they are flexible they are known as flexible imaging bundles.[2]
High fiber count and small fiber size corresponds to higher image resolution.[2] Each fiber is like one pixel.
Uses
Image bundles can be used to masswise decouple components of a near-eye display such that the electrooptic modulation and driver circuitry happens in a physically separate location from the user's face.
A light field display device can be built using a large number of flexible image conduits. Each flexible image conduit can be optically coupled to one microlens on the output side, and one generated view on the input side.
