A Flat-Field Diffractive Landscape Lens: Design And Performance
暂无分享,去创建一个
A single diffractive lens with a separated aperture stop can be corrected for third-order coma, astigmatism, and Petzval curvature of field. This simple system provides a high quality imaging over a much wider field of view than conventional optically recorded holographic optical elements. This lens is compared with other lenses using modulation transfer function techniques. The correction of spherical aberration is achieved with a suitably designed Schmidt-camera-type aspheric corrector plate. The telecentric layout and distortion of the lens are shown to be suitable for use as a Fourier transform lens.
