Receiver Optics & Small Aperture Telescopes Optics Parallel Session
Post session talks here.
Notes from sessions
Take notes here.
Requirements flow from science to telescopes
beam size & sensitivity vs. freq
- min sizes of telescopes
- number of detectors in each band on each telescope size
grouping of bands on telescopes
- matched beams?
- simultaneous measurements with concentric beams?
scattering & sidelobe level, stability (mechanical & thermal)
- how to specify this
scan speed, pattern vs. freq
- pointing & tracking requirements
- does scan strategy need multiple, independent mounts?
calibration
- which sources do we need to see? how often?
- do we need planets?
Site & ops to telescopes
site specific conditions
- temp, seismic, insolation, rain/snow
power constraints
shipping
uptime & maintainability
- do we need several telescopes/mounts?
Requirements flow within telescopes (trade studies, allocations, good practice, prejudice)
tel size vs. ell
- small tels for low ell?
reflectors vs. refractors
tel optical layout
tel mount layout
number of each type of telescope
shield config
can we tolerate panel gaps on big telescopes?
boresight rotation to fix tel errors?
manufacturability
Requirements flow to/from cameras
subfield cameras? (yes requires 1st lens at tel focus)
tel focal ratio (not necessarily same as at detectors)
limits/rqts on camera orientation/motion/accel
tel boresight rotation to fix residual camera beam/pol errors
- instrument rotation may be easier
drive noise (EMI, vibration, magnetic)
access to camera (frequency, specific orientation)
