description An optical component includes a transparent substrate, a first volume grating and a second volume grating disposed on the transparent substrate. The transparent substrate is located between the first volume grating and the second volume grating. The first volume grating has a plurality of first diffraction elements arranged in rectangular array, while the second volume grating has a plurality of second diffraction elements arranged in rectangular array. In addition, the spacing between two adjacent first diffraction elements is larger than the spacing between two adjacent second diffraction elements.
