摘要：
A non-mechanical beamsteerer can be provided to adjust an angle of a light beam, such as to scan the light beam over a field of regard. The non-mechanical beamsteerer can include a first collection of steering elements that are smaller than a size of a light beam. The first collection of steering elements can adjust the angle of the light beam by diffracting the light beam. The non-mechanical beamsteerer can also include a second collection of steering elements that are larger than a size of the light beam. The second collection of steering elements can adjust an angle of the light beam by refracting the light beam. The non-mechanical beamsteerer can operate without a compensation plate, such as to provide a reduced size of the beamsteerer and an increased acceptance angle of the beamsteerer.
