An experimental polarimeter by Dr. Jiri Polivka:
Return to homepage
- Dr. Jiri Polivka was enthused with my polarimeter experiments and
built his own improved
(408k) switching dual-channel detector to go with a 30 cm TVRO dish
(19.11.2007)
- here is a photograph
(191k) of the setup he first used for successful addition and subtraction
(12k) Stokes parameter transit detection of the solar flux
(19.11.2007)
- the antenna was manually scanned at low elevation (the hotter noise
level at the right is from a nearby wall, the 30 cm dish beamwidth is
approx. 7 degrees)
- the latest comment: "I need a bigger antenna" - now where have I
heard that one before... ?
- another solar
transit scan with the subtraction channel; the drift at the
beginning of the scan is most likely due to the equipment still warming
up.
- more to come !
