Abstract

A teleprompter includes an optical assembly and an accommodating space for accommodating an electronic device including a lens and an image display unit configured to emit a light along a first path. The optical assembly includes a light-reflecting unit and a beam-splitting unit. The light-reflecting unit is configured to divert the light from the first path to a second path and has a first light-reflecting portion facing the image display unit. The beam-splitting unit is on the second path and configured to allow a first portion of the light to transmit and divert a second portion of the light from the second path to a third path having a same direction as an optic axis of the lens. A unit vector {circumflex over (r)}1 along the second path, a unit vector {circumflex over (r)}2 along the third path, and a unit normal vector {circumflex over (n)}1 of the first light-reflecting portion satisfy an equation: {circumflex over (r)}2={circumflex over (r)}1−2({circumflex over (r)}1·{circumflex over (n)}1).

Claims17

Dependent claims

A teleprompter, comprising:

an accommodating space configured for accommodating an electronic device, wherein the electronic device comprises an image display unit and a lens, and the image display unit is configured to emit a light along a first path;
and
an optical assembly disposed in the accommodating space, on a side of the electronic device, and comprising:
a light-reflecting unit configured to divert the light from the first path to a second path and having a first light-reflecting portion, wherein the first light-reflecting portion is disposed on the first path and faces the image display unit;
and
a beam-splitting unit disposed on the second path and facing the lens and configured to allow a first portion of the light to transmit and to divert a second portion of the light from the second path to a third path, wherein the third path has a same direction as a direction of an optic axis of the lens, and a unit vector {circumflex over (r)}1 along the second path, a unit vector {circumflex over (r)}2 along the third path, and a unit normal vector {circumflex over (n)}1 of the first light-reflecting portion of the light-reflecting unit satisfy an equation:
{circumflex over (r)}2={circumflex over (r)}1−2({circumflex over (r)}1·{circumflex over (n)}1).
