A light detection and ranging (LIDAR) sensor system includes a window, a laser source configured to generate a beam, one or more scanning optics configured to output the beam through the window, and a sensor. The sensor includes at least one light emitter configured to output light associated with a parameter different than a corresponding parameter of the beam, a first optic coupled to the window, the first optic configured to receive the light from the light emitter and provide the light into the window to undergo total internal reflection in the window, a second optic coupled to the window, the second optic configured to receive the light provided into the window by the first optic, and a detector configured to receive the light from the second optic and output a signal indicative of a presence of an obscurant on the window.

Techniques for generating an arbitrary target electromagnetic signal with a nonlinear material, include determining a time varying target amplitude and target phase and an order n of a nonlinear material. For each time, a first set of nth roots of the target amplitude and a second set of nth roots of the target phase are determined. An input amplitude based on one value from the first set and an input phase based on one value from the second set is determined at each time. A difference between temporally successive values of phase is minimized. An electromagnetic signal is modulated to impose the input amplitude and phase to produce a modulated electromagnetic input signal that is introduced into the nonlinear material to produce a target electromagnetic signal.
