CURVED VOLUME PHASE HOLOGRAPHIC (VPH) DIFFRACTION GRATING WITH TILTED FRINGES AND SPECTROGRAPHS USING SAME |
摘要 |
The subject matter described herein includes a curved VPH grating with tilted fringes and spectrographs, both retroreflective and transmissive, that use such gratings. A VPH grating according to the subject matter described herein includes a first curved surface for receiving light to be diffracted. The grating includes an interior region having tilted fringes to diffract light that passes through the first surface. The grating further includes a second curved surface bounding the interior region on a side opposite the first surface and for passing light diffracted by the fringes. |
