Abstract: A fingerprint image capturing module includes a light-emitting element, a first optical element having two light-reflecting structures and a light-guiding structure, a second optical element, a lens assembly, and a fingerprint image sensing element. A projection light beam generated by the light-emitting element is projected onto the light-reflecting structure, the projection light beam is reflected by the light-reflecting structure to form an illumination light beam that passes through a light-transmitting element and is projected onto a fingerprint. The illumination light beam is reflected by the finger to form an image light beam that is projected onto the light-guiding structure and guided by the light-guiding structure, the image light beam passes through the lens assembly and is projected onto the fingerprint image sensing element through the second optical element, and the fingerprint image sensing element receives the image light beam to obtain a fingerprint image of the fingerprint.

Abstract: A wireless transmission device for a computer peripheral includes a receiving module and an emitting module. The emitting module includes a control unit, at least one light-emitting component formed on the control unit, and an optical module. Whereby a signal light emitted by the light-emitting component is diffused by the optical module and then is non-directionally radiated into the air thereby realizing a multidirectional and multi-wideangle signal transmission for being readily received by the receiving module.

Abstract: An optical signal receiving device comprising a ring-shaped body, a control unit, an optoelectronic unit and a convex lens. The ring-shaped body has a receiving surface arranged on the outer surface thereof. The receiving surface has a first reflection surface and a second reflection surface on top surface and bottom surface thereof and parallel to each other. A bent block is formed on inner side of the ring-shaped body and a focusing surface is formed at distal end of the bent block. The control unit and the optoelectronic unit are arranged within the ring-shaped body and the convex lens is arranged atop the ring-shaped body. The light from top and lateral direction is guided by the convex lens and the ring-shaped body to the optoelectronic unit.

Abstract: A light transceiver apparatus comprises a receive module and an emitting module. The emitting module has a control unit with light emitting element. The light emitted from the light emitting element forms a wide-angle light and propagates to the receive module through one or multiple reflection. A plurality of light emitting elements is arranged uniformly and a lens is arranged atop the light emitting elements to provide a wide-angle light in omni-direction. The light from the light emitting element propagates, through direct or indirect transmission path, to the receive module.
