    摘要: A forward viewing device allows a cyclist having a head down position to view a scene forward of a bicycle. The device includes a prism fixed to a support which is connected to the bicycle forward of the cyclist. An image of the scene is transmitted through a forward facing surface of the prism, reflected internally by at least two surfaces of the prism, and transmitted to the cyclist through a prism surface as an image which is not mirrored left to right or turned upside down. In an embodiment, multiple prisms are positioned with adjacent ends, to increase the horizontal field of view. In another embodiment, multiple prisms are offset vertically, to increase the vertical field of view. In another embodiment, the device has a single optical element and does not require alignment.
