The Wide-field High-resolution Infrared Telescope (white)
TheWide-field High-resolution Infrared TElescope (WHITE) will be dedicated in the first years of its life to carrying out a few (well focused in terms of science objectives and time) legacy surveys. WHITE would have an angular resolution of ∼ 0.3′′ homogeneous over ∼ 0.7 sq. deg. in the wavelength range 1μm to 5μm, which means that we will very efficiently use all the available observational ti...
متن کاملWide-field, high-resolution Fourier ptychographic microscopy
In this article, we report an imaging method, termed Fourier ptychographic microscopy (FPM), which iteratively stitches together a number of variably illuminated, low-resolution intensity images in Fourier space to produce a wide-field, high-resolution complex sample image. By adopting a wavefront correction strategy, the FPM method can also correct for aberrations and digitally extend a micros...
متن کاملWide-field Corrector for a Gregory Telescope
A form of prime focus corrector for the Gregory system is proposed that provides the sub-arcsecond field of view up to 3 in diameter for the spectral range 0.35 − 0.90 microns. The corrector includes five lenses made of same glass (fused silica is preferable). The distinctive feature of the corrector consists in dissimilar use of the central and edge zones of a front lens disposed in the exit p...
متن کاملThe CCAT 25 m diameter submillimeter-wave telescope
CCAT will be a 25 m diameter telescope operating in the 2 to 0.2 mm wavelength range. It will be located at an altitude of 5600 m on Cerro Chajnantor in Northern Chile. The telescope will be equipped with wide-field, multi-color cameras for surveys and multi-object spectrometers for spectroscopic follow up. Several innovations have been developed to meet the <0.5 arcsec pointing error and 10 μm...
متن کاملMiniaturized high-resolution wide-field contact lens for panretinal photocoagulation
BACKGROUND AND OBJECTIVE We describe a miniaturized lightweight high-refractive-index panretinal contact lens for diagnostic and therapeutic visualization of the peripheral retina. INSTRUMENT DESIGN The miniaturized high-resolution wide-field contact lens includes three optical elements in a light (15 g) and miniaturized (16 mm footplate, 24 mm external aperture, and 21 mm vertical height) ca...
