This image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Force components of optical lift, generated model.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
This image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}. For more information, see {{BadJPEG}}.
Summary
DescriptionForce components of optical lift, generated model.jpg
English: A bundle of rays are incident on a lightfoil from the left. Through refraction and reflection, each ray imparts some momentum at every surface of the lightfoil. These discrete momentum transfers are shown in the form of surface normal forces - green lines. Summing the momentum imparted from every ray results in a total force from the center of mass with lifting and scattering components and a total torque - shown here as inducing clockwise rotation. This specific case is for a lightfoil in the shape of a semi-circular rod oriented with an angle of attack, alpha, of about 10°.
