1. A method of warning a driver of a vehicle of an obstacle that is more than one kilometer from the vehicle, the method comprising the steps of:

  • emitting MIR laser energy from the vehicle, the laser energy having a wavelength approximately between 3500 nanometers and 5000 nanometers;

    using a phase conjugate lens to orthogonally direct a portion of the laser energy that is reflected by the obstacle to an image-capturing device or sensor within the vehicle; and

    displaying an image of the obstacle to the driver, the image being based on the laser energy directed to the image-capturing device.
