摘要：
Apparatus and methods for using a tunable optical source in safety curtain applications provide for enhanced operation of the safety curtain. In an embodiment, a safety curtain includes a transmit unit and a receive unit to operate as the safety curtain, where a single tunable light source generates different wavelengths of light and a single detector is used to detect the generated light.
