The first polarimeter in astronomy to use a stress-engineered optic (SEO)

We present a new single-shot, full-Stokes optical astro-polarimeter design using stress-engineered optics (SEOs). The SEO is a cylindrical glass window under static stress by radially-inward forces in three symmetrically-space regions, producing spatially-varying birefringence throughout (Spilman and Brown, Applied Optics IP, 46, 2007), and can be produced by using o-the-shelf supplies and some machining. By collimating light collected by a telescope through the SEO and then focusing it onto a detector, the system's point spread function (PSF) acquires a shape uniquely dependent on the full polarization vector of the input light (Beckley and Brown, Proc. SPIE, 757011, 2010). By measuring the imaged PSFs, the full-Stokes polarization states of all point sources (stars) in the field can ideally be determined from a single exposure and without division of amplitude techniques. Prior to our instrument, these techniques and technology had not yet been applied to astronomy. Aside from filter wheels and focusing elements, our instrument contains no moving parts. The instrument will operate by first taking a set of calibration exposures of 100% polarized light using swap-in polarizers in one of its filter wheels. Once the calibration images are taken, the polarizers are removed form the light path, and the science target (star) is imaged. Using techniques described in this paper, the calibration images allow one to determine the unknown polarization of the science target. This process is repeated in multiple photometric bands at visible wavelengths for color-dependent studies. The successful application of this polarimeter technology in astronomy would mark a step forward for increasing polarimetry efficiency (no temporal modulation required) and simplicity of instrumentation (no spatial modulation required). Contained in this paper are the on-sky commissioning results of our polarimeter on an 0:2m (8in) telescope at the University of Denver, and an in-depth look at the effect of Earth's atmospheric turbulence on the polarization-dependent PSF detection. We have also begun testing the instrument's capabilities in measuring both linear and circular interstellar polarization, and a look at the variability of historic polarized and unpolarized "standard" stars. Better understanding of the interstellar component of the polarization of stars and the nature of calibration stars are required for all future polarimetric measurements. The authors are grateful to the estate of William Herschel Womble for the support of astronomy at the University of Denver.

In 1929, a grant from Eastman Kodak and Bausch and Lomb established The Institute of Optics as the nation's first academic institution devoted to training optical scientists and engineers. The mission was 'to study light in all its phases', and the curriculum was designed to educate students in the fundamentals of optical science and build essential skills in applied optics and optical engineering. Indeed, our historic strength has been a balance between optical science and engineering--we have alumni who are carrying out prize-winning research in optical physics, alumni who are innovative optical engineers, and still other alumni who are leaders in the business community. Faculty who are top-notch optical engineers are an important resource to optical physics research groups -- likewise, teaching and modeling excellent optical science provides a strong underpinning for students on the applied/engineering end of the spectrum. This model -an undergraduate and graduate program that balances fundamental optics, applied optics, and optical engineering- has served us well. The impressive and diverse range of opportunities for our BS graduates has withstood economic cycles, and the students graduate with a healthy dose of practical experience. Undergraduate advisors, with considerable initiative from the program coordinator, are very aggressive in pointing students toward summer research and engineering opportunities. The vast majority of our undergraduate students graduate with at least one summer of experience in a company or a research laboratory. For example, 95% of the class of 2008 spent the summer of 2007 at companies and/or research laboratories: These include Zygo, NRL, Bausch and Lomb, The University of Rochester(The Institute of Optics, Medical Center, and Laboratory for Laser Energetics), QED, ARL Night Vision laboratories, JPL, Kollsman, OptiMax, Northrup Grumman, and at least two other companies. It is an impressive list, and bodes well for the career preparation for these students. While this extracurricular experience is truly world-class, an integrated design experience defined within our academic program is increasingly necessary for those going on to professional careers in engineering. This paper describes the philosophy behind a revision to our undergraduate curriculum that integrates a design experience and describes the engineering laboratory that has been established to make it a reality. The laboratory and design center has been named in honor of Robert E. Hopkins, former director and professor, co-founder of Tropel corporation, and a lifelong devotee to engineering innovation.
