Design and Fabrication of Silicon-Blazed Gratings for Near-Infrared Scanning Grating Micromirror

Sinong Zha et al.

Summary: This paper presents the design and fabrication of a high diffraction efficiency silicon-blazed grating for spectral analysis instruments. The grating has a diffraction efficiency greater than 33.23% in the spectral range of 800-2500 nm, reaching a maximum of 85.62% at the blaze wavelength of 1180 nm. The grating is integrated into a scanning micromirror to achieve optical splitting and scanning. The results demonstrate high diffraction efficiency for potential near-infrared spectrometer applications.

Blazed grating pupil remapping and rotational synthesis with computational phase correction for a two-aperture system

Sarah E. Krug et al.

Summary: Multi-aperture imaging systems can reduce the size, weight, and cost of an imaging system while maintaining resolution. Using anamorphic pupil remapping and computational phase correction algorithm can reduce field dependent contrast and lead to piston corrections for partially coherent illumination. Rotational aperture synthesis can combine piston corrected images and increase resolution in multiple axes.
