Call for
Papers
In December 1920, Michelson and Pease measured the first angular diameter of a star, the red giant Betelgeuse, using the 100 inch telescope on Mt Wilson configured as a ground-breaking optical interferometer. One hundred years have passed, and the modern descendants of Michelson’s interferometer can now routinely produce images of stellar surfaces, witness exoplanets in orbit and probe the structures of active galactic nuclei. For the last few decades, topically focused SPIE meetings have continued to play a unique role in fostering our field: this is the singular venue that brings together interferometrists from the world over.

Against a background of a challenging funding environment worldwide, our previous meeting (Austin, 2018) showed very exciting progress in overcoming some of the most firmly entrenched obstacles that have long plagued the field. In particular, widespread scientific relevance to a broad cross-section of the astronomical community has long been hampered by the issue of sensitivity. Progress on several fronts, such as the roll-out of active/adaptive wavefront correction, as well as dramatic enhancements in low-noise detector technologies, now promises to finally unleash “stellar interferometry” from its traditional niche within stellar physics, perhaps calling for our community to rethink its identity as working in “astrophysical interferometry." The wealth of exciting results from the past two years gives testimony to these ongoing rapid developments.

The primary goals of this conference are to allow the attendees to learn firsthand about the exciting capabilities found in facilities across the globe and to discuss the future prospects for interferometry in technology and instrumentation. Its primary focus will be on the latest innovations in technology and engineering for ground- and space-based interferometry in the optical and infrared, including new instrumentation, techniques and software. Scientific results will be highlighted, with priority given to findings that push current facilities to their limits and/or exploit innovative techniques and technologies. Results should particularly serve to illustrate novel observations or analytical techniques.

Invited talks and panel discussions will feature in the program, however most time will be competitively allocated based on the response to this Call for Papers. We solicit contributed papers on these and related topics:
  • Observing techniques in astrometry, imaging, nulling, aperture masking, speckle interferometry, precision calibration, high-dynamic range methods, absolute or differential phase and closure phase, polarimetry, double Fourier techniques, intensity interferometry.
  • Technologies such as new detectors, fiber optics, integrated optics, single-mode filtering, achromatic phase delays for nulling, delay lines.
  • Critical subsystems including wavefront control, fringe tracking, cryogenics, control algorithms, star tracking, beam combination, picometer metrology, vacuum systems.
  • Space (or near-space) interferometry especially new mission concepts, cost-effective designs, pathfinders, and connection with the FIR space community.
  • Data processing and analysis, robust data calibration, image reconstruction algorithms, publicly-available tools, data interpretation and modeling.
  • Facility issues including long-term monitoring, performance characterization, auto-alignment, data archive, vibration mitigation and control.
  • Current and planned facilities and instruments, including next generation instruments and possible improvements or revamping of current facilities.
  • Introspection and brainstorming for the long-term future of interferometry, science and technical opportunities, new directions in times of limited funding.
We expect a large number of submitted abstracts and the program committee will actively assign contributed papers to be either oral or poster, unless the author requests poster presentation. Students who received or expect to receive their Ph.D.s after January 1, 2019, should include the word “THESIS” in their abstract titles to be eligible for the “Best Dissertation” prize to be awarded during the conference.

All presenters will be asked to provide a manuscript in advance of the meeting for publication in a proceedings volume to be published on the SPIE Digital Library soon after the conference.
