Yet, only a tiny fraction of the worldwide investment in technology directly targets the needs of astronomy, so astronomers must seek to leverage and harness technology advancements made for other purposes. In this presentation, I will explore the various ways this has been done for three major recent advances in the study of black holes: the detection of merging black holes with LIGO in 2016, the radio imaging of M87’s supermassive black hole with EHT in 2019, and the decades-long studies of stellar motions near the galactic center, which revealed the central black hole in our galaxy and is the subject of the 2020 Nobel prize. In each case, the technology story spans decades, and involves a combination of advances in several areas.","PeriodicalId":255503,"journal":{"name":"Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation IV","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127449293","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}

Its design is based on a virtually imaged phased array instead of an echelle grating, which allows the spectrometer to fit inside a 0.2m3 cryostat, and results in a gain in throughput with respect to usual echelle spectrographs. One specific science case that can benefit from this new type of design is the characterization of exoplanets' atmosphere.

In this paper we briefly summarize our past work, and then discuss (a) two years’ field testing of our design with NiO; (b) efforts to find other materials that play the same role as NiO in improving durability; and (c) tests with ScF3 that show good results as a replacement for YF3/YbF3 but with improved optical properties.

Super-resolution technology which breaks the diffraction limit of the imaging system can enhance the spatial resolution with compact setup and low cost. In this work, a novel super-resolution telescopic imaging method based on aperture modulation is proposed, and two different algorithms based on intensity extrapolation and image reconstruction for the recovery of super-resolution image are demonstrated respectively. With the help of aperture modulation, redundant information which contains high frequency components beyond the cut-off frequency of the imaging system is coded into the image sequence, and then they are extracted and used to reconstruct the super-resolution image by subsequent signal processing. Experimental results showed that the resolution was enhanced by 2.1 times for extended targets, and 3 times for point sources. Better performance is possible with the improvement of algorithm.","PeriodicalId":255503,"journal":{"name":"Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation IV","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134177757","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}

In this paper, we present a new method for the fabrication of variable filters with different spatial profiles based on plasma assisted reactive magnetron sputtering. Variable filters are based on the variation of the thickness of the layers deposited on the substrate. The layers are manufactured using a Buhler HELIOS machine. To insure a non-uniformity of the deposited layers, adapted masks are placed in front of the targets for the low and high refractive index materials. The uniformity of these layers is measured via a homemade set-up allowing a local measurement of the transmission over the component surface. We demonstrate the fabrication of a narrow variable filter where all the thicknesses of all layers are changing, resulting in an overall shift of the filter.","PeriodicalId":255503,"journal":{"name":"Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation IV","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127925576","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}

Most traditional manufacturing techniques cannot yield polished freeform optical surfaces. Likewise, traditional metrology equipment has difficulty accurately measuring the deviation of freeform surfaces from their nominal shape, the surface form error. The freeform manufacturing process requires control of both the surface form and the surface location simultaneously. The combination of both surface location and form error is referred to as total error. Inclusion of mechanical fiducials on freeform optics allows for precise locating of all surfaces of an optic in reference to one another and provide a reference from which the freeform surface can be measured against. Alignment fiducials enable more precise measurement of total error and can also aid in alignment of the optic in the final assembly and test.","PeriodicalId":255503,"journal":{"name":"Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation IV","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116155669","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}
