Typically, imaging a star system to find an exoplanet requires significant attenuation of the host star’s high flux in order to detect the much weaker planetary light. The most common method to do this is coronagraphy, which blocks the starlight with an amplitude mask or a null inducing phase mask [1]. An alternative and attractive method is nulling interferometry where light from multiple telescopes are used to simultaneously form a high resolution image (or its Fourier components) and also to form a null in the vicinity of the host star, thereby attenuating it [2]. This has the advantage over coronagraphy that it is not limited to using a single telescope and is thus able to probe deeper into a star system by virtue of the higher resolution available by an interferometric array.","PeriodicalId":131350,"journal":{"name":"Micro + Nano Materials, Devices, and Applications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133804901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expected spatial resolution by the GLAO correction is about 0.2 arcsec FWHM in K-band under moderate seeing conditions at Subaru telescope. ULTIMATE-Subaru will provide a unique capability to realize wide-field and high spatial resolution survey observations in near infrared in the era of TMT.

In this work, the mass of the mirrors is reduced by using space approved carbon fiber reinforced polymer (CFRP) material and employing micro-fiber composite (MFC) actuators for aberration correction and phase manipulation in an active/adaptive optical mirror system. The carbon fiber mirror is fabricated with 16 layers of prepreg composite MTM44- 1/IMS65 carbon fiber and one layer of polishable resin. The layers are cured under pressure in an autoclave machine in a pressure and temperature-controlled environment. 2 different piezoelectric actuators, Push actuators and MFC actuators, are tested and the phase shift, form factor and surface deformation due to the active actuators are compared. Push actuators are the most common means of active optics. CFRP structure and surface deformation after actuator’s effect are investigated theoretically using finite element analysis with the aid of COMSOL software and by optical experiments.","PeriodicalId":131350,"journal":{"name":"Micro + Nano Materials, Devices, and Applications","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117021875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While conventional approaches rely on bulky components to access and filter the Fourier plane content of a wavefield, nanophotonic approaches for spatial frequency filtering have recently gained attention. Here computational and experimental progress towards the design and demonstration of metasurfaces with spatial frequency filtering capability for optical image processing will be presented. Using the example of a metasurface consisting of radial rod trimers we demonstrate its potential to perform edge enhancement in an amplitude image and conversion of phase gradients in a wavefield into intensity modulations.
