Abstract
In one embodiment, an optical device comprising an emitter, first and second emitter optical elements and a receiver is disclosed. The emitter and the receiver may be arranged substantially along a longitudinal axis. The first and second emitter optical elements may be interposing the longitudinal axis. One other embodiment discloses an optical device comprising an emitter and a receiver arranged on a longitudinal axis. The optical device may further comprise first and second emitter optical elements arranged along an axis orthogonal to the longitudinal axis but interposing the longitudinal axis. In another embodiment, a proximity sensor having first and second emitters interposing a longitudinal axis is disclosed.
