    • A system including a first radiation source providing a first beam and a second radiation source providing a second beam, and a radiation sensor, wherein the first beam does not overlap the second beam. In some embodiments, the radiation comprises infrared radiation. A gesture recognition system including at least one infrared sensor, a first infrared light emitting diode (LED) providing a first far-field radiation beam that extends from the first infrared LED and defines a first central ray, a second infrared light emitting diode (LED) providing a second far-field radiation beam that extends from the second infrared LED and defines a second central ray, wherein the first central ray and the second central ray define a single intersection point and an angle of intersection.
    • 一种系统,包括提供第一光束的第一辐射源和提供第二光束的第二辐射源,以及辐射传感器,其中第一光束不与第二光束重叠。 在一些实施例中,辐射包括红外辐射。 一种手势识别系统,包括至少一个红外传感器,第一红外发光二极管(LED),其提供从第一红外LED延伸并限定第一中心射线的第一远场辐射束,第二红外发光二极管 )提供从所述第二红外LED延伸并限定第二中心射线的第二远场辐射束,其中所述第一中心射线和所述第二中心射线限定单个交叉点和交叉角。
