Abstract
An optical interferometer () is used to determine information about the position, gradient or motion of a surface of an object () at each of a plurality of points on the surface. An image is projected onto the surface of the object (), such that, for each of the plurality of points, the intensity or spectrum of the projected image at that point depends on the determined information about the position, gradient or motion of the surface at that point.
