Claim 19:
20. A system, comprising:
a remote control system, comprising:
a first radiation source configured to generate an infrared radiation projection to control a device;
a second radiation source configured to generate a visible radiation projection; and
an optical controller configured to adjust one or more parameters associated with the infrared radiation projection before the infrared radiation projection is emitted to the device and to adjust one or more parameters associated with the visible radiation projection before the visible radiation projection is emitted to the device,
wherein the one or more parameters associated with the infrared radiation projection comprise one or more of convergence or divergence of the infrared radiation projection, a polarization of the infrared radiation projection, or an energy of the infrared radiation; and

a receiver device located at the device to be controlled, the receiver device configured to receive the infrared radiation projection to generate a control signal for controlling the device.
