Notch Filter Masks: Practical Image Masks for Planet-Finding Coronagraphs
An ideal coronagraph with a band-limited image mask can efficiently image off-axis sources while removing identically all of the light from an on-axis source. However, strict mask construction tolerances limit the utility of this technique for directly imaging extrasolar terrestrial planets. We present a variation on the basic band-limited mask design—a family of “notch filter” masks—that mitig...
متن کاملA Unified View of Coronagraph Image Masks
The last few years have seen a variety of new image mask designs for diffraction-limited coronagraphy. Could there still be useful designs as yet undiscovered? To begin to answer this question, I survey and unify the Fraunhofer theory of coronagraph image masks in the context of a one-dimensional classical coronagraph. I display a complete solution to the problem of removing on-axis light assum...
متن کاملAlternative Masks for Nanolithography
The use of masks coming from research field as different as colloids, polymers or nanomaterials is a recently emerging field. Recent advances in this area have developed a variety of practical routes which have a great potential to overcome or at least complete the high-cost lithographic techniques. This review focuses on three techniques that try to reduce to the nanometer range, the size of t...
متن کاملWearing masks in a pediatric hospital: developing practical guidelines.
During the outbreak of Severe Acute Respiratory Syndrome (SARS) in the spring of 2003, strict infection control measures were implemented in Toronto and surrounding hospitals. These measures included extreme restrictions on those who would normally accompany patients to the hospital, screening for SARS, and protective attire for hospital staff, including masks, face shields, goggles, gloves and...
متن کاملDesign of Farthest-Point Masks for Image Halftoning
In an earlier paper, we briefly presented a new halftoning algorithm called farthest-point halftoning. In the present paper, this method is analyzed in detail, and a novel dispersion measure is defined to improve the simplicity and flexibility of the result. This new stochastic screen algorithm is loosely based on Kang’s dispersed-dot ordered dither halftone array construction technique used as...
