Abstract
A compact displacement sensor comprises a light intensity pattern object, a micro-lens array and an imaging device including a light-intensity measuring surface. The micro-lens array is disposed between the light intensity pattern object and the imaging device such that each micro-lens focuses a corresponding sub-image making up a portion of the light-intensity pattern on the light-intensity measuring surface to create thereupon an image of the object comprising an array of focused sub-images. The displacement sensor can provide high resolution measurements of displacement of the light intensity pattern object from a reference position by registering subsequent images captured after a change in relative position between light intensity pattern object and the imaging device to a reference image based on pattern portions in the focused sub-images.
