System and method for increasing the diffraction efficiency of holograms |
摘要 |
A resonator system is disclosed for use in illuminating a diffractive element. The system includes a source of an electromagnetic field having a wavelength of lambd, and first and second optical elements, each of which is at least partially reflecting. The first and second optical elements are separated from one another such that the optical path between the optical elements has a distance <math-cwu id="MATH-US-00001"> <number>1</number> <math> <mrow> <mrow> <mrow> <mo>(</mo> <mrow> <mrow> <mn>2</mn> <mo>it</mo> <mi>m</mi> </mrow> <mo>+</mo> <mn>1</mn> </mrow> <mo>)</mo> </mrow> <mo>it</mo> <mfrac> <mi>lambda</mi> <mn>4</mn> </mfrac> </mrow> <mo>,</mo> </mrow> </math> <mathematica-file id="MATHEMATICA-00001" file="US20030035160A1-20030220-M00001.NB"/> <image id="EMI-M00001" wi="216.027" he="17.03835" file="US20030035160A1-20030220-M00001.TIF" imf="TIFF" ti="MF"/> </math-cwu> wherein m is an integer.
