The invention provides a spatially-selective reflective structure for the detection of submillimeter electromagnetic waves and systems and methods incorporating spatially-selective reflective structures. One aspect of the invention provides a spatially-selective reflective structure including a partially-conducting slab and a modulating reflector disk adjacent to the partially-conducting slab. The modulating reflector disk includes a plurality of modulations. Another aspect of the invention provides a submillimeter imaging device including submillimeter wave optics, a spatially-selective reflective structure located in the focal plane of the submillimeter wave optics, a submillimeter wave receiver positioned to capture waves reflected from the spatially-selective reflective structure, and a motor configured to rotate the spatially-selective reflective structure. The spatially-selective reflective structure includes a partially-conducting slab and a modulating reflector disk adjacent to the partially-conducting slab. The modulating reflector plate includes one or more modulations.

Spatially-selective reflector structures, reflector disks, and systems and methods for use thereof

One aspect of the invention provides a spatially-selective disk including a plurality of holes arranged such that a matrix having a plurality of rows, each row having elements corresponding to a fraction of a pixel in a viewing window projected onto the disk that is backed by a hole at a distinct rotational position of the disk, has linearly independent rows. Another aspect of the invention provides a spectrometry device including: a disk having one or more holes; a motor configured to rotate the disk; one or more beam-shaping optics arranged to map one or more spectral components of radiation of interest onto a plurality of locations on the disk; and a receiver positioned to capture the one or more spectral components passing through the one or more holes as the disk is rotated.
