4. Design of optical components

Invited Talks

Invited Talk

Nowadays there is a considerable scientific interest in increasing the field of view of submillimeter wave observatories in order to enable a much faster wide field mapping. This would enable telescopes to survey large regions of molecular clouds and image nearby galaxies.
We present our study of multi-pixel architectures that could allow for orders of magnitude increase in mapping speeds,...

13. Heterodyne Array Receivers for Space and Ground Based Applications

Invited Talks

Invited Talk

Heterodyne array receivers have been successfully built for ground-based telescopes. Here we will present the first detailed design for a space application, the Heterodyne Receiver for the Origins Space Telescope (HERO). HERO follows the traditional design, but limited cooling power and the limited electrical power of the satellite pose major challenges. Minor challenges are limited...
