A device includes an image sensor, first optics, second optics, and a processor. The first optics are configured to form a first optical pattern (OP) on the image sensor. The first OP is associated with a first wavelength. The second optics are configured to form a second OP on the image sensor. The second OP is associated with a second wavelength that is longer than the first wavelength. The processor is configured to generate a first turbulence estimate based on relative motion of the first OP, to generate a second turbulence estimate based on relative motion of the second OP, and to generate error correction data. The processor is also configured to adjust the first turbulence estimate based on the error correction data and the second turbulence estimate to determine an estimated turbulence value. The processor may also be configured to estimate a wind profile, a turbulence profile, or both.
