Abstract
An apparatus for ultrasensitive long-wave imaging cameras is provided. In one embodiment, the apparatus includes a filter configured to allow high frequencies of interest to pass through the filter. The apparatus also includes an antenna that is configured to receive the high frequencies of interest. The apparatus further includes a plurality of bolometers that are configured to measure data regarding the high frequencies of interest.
Claims17
An apparatus, comprising:
- a filter configured to allow high frequencies of interest to pass through the filter;
- an antenna configured to receive the high frequencies of interest;
- a plurality of bolometers configured to measure data regarding the high frequencies of interest received by the antenna;
- a dielectric coating between the antenna and the filter configured to increase an absorption bandwidth;
- and
- a resonant absorber configured to reflect the high frequencies of interest received from the filter back to the antenna.
An apparatus, comprising:
- a quasioptical filter configured to prevent frequencies below a cut-off from passing through the filter;
- an antenna with a single slot having a plurality of tap points configured to receive and measure high frequencies of interest ranging between 1 terahertz and 10 terahertz;
- a dielectric coating between the antenna and the filter configured to increase an absorption of the frequencies of interest;
- and
- a resonant absorber configured to reflect the high frequencies of interest received from the filter back to the antenna.
An apparatus, comprising:
- a quasioptical filter configured to prevent frequencies below a cut-off from passing through the filter;
- an antenna with a plurality of slots, each slot configured with a plurality of tap points to receive high frequencies in order to allow measurements of high frequencies of interest ranging between 1 terahertz and 10 terahertz;
- a dielectric coating between the antenna and the filter configured to increase an absorption of the frequencies of interest;
- and
- a resonant absorber configured to reflect the high frequencies of interest received from the filter back to the antenna.
