摘要 |
An adjustable lens is disclosed for use in an optical profilometer system. The adjustable lens includes a plurality of elements that are mutually spaced from another in a first position and provides a first focal point for an incident electromagnetic field having a first frequency incident at a first angle with respect to the plurality of elements. The adjustable lens also includes an actuation unit for changing the focal point of the plurality of elements to provide a second focal point for the incident electromagnetic field having the first frequency incident at the first angle with respect to the plurality of elements.
