TOWARDS a METAMATERIALLY-BASED ANALOGUE SENSOR FOR TELESCOPE EYEPIECES jeremy batterson.

(NB: Those familiar with photography or telescopy can skip over the “elements of a system,” since they will already know this.)

In many telescopic applications, what is desired is not a more magnified image, but a brighter image. Some astronomical objects, such as the Andromeda galaxy or famous nebulae like M42 are very large in apparent size, but very faint. If the human eye could see the Andromeda galaxy, it would appear four times wider than the Moon. The great Orion nebula M42 is twice the apparent diameter of the Moon.

Astrophotographers have an advantage over visual astronomers in that their digital sensors can be wider than the human pupil, and thus can accommodate larger exit pupils for brighter images.

The common three-factor determination of brightness of a photograph (aperture, ISO, and shutter speed) should actually be five-factor, including what is often left out since it had already been inherently designed into a system: magnification and exit pupil. The common factors are.

Elements of a system: 1 )Aperture. As aperture increases, the light gain of a system increases by the square of increased aperture, so a 2-inch diameter entrance pupil aperture has four times gain over a 1-inch diameter entrance pupil and so on.

Today, at a special AR/VR focused event held inside its virtual reality community platform Altspace, Microsoft showcased a new product aiming to provide their AR HoloLens platform and VR Windows Mixed Reality platform with a shared platform for meetings.

The app is called Microsoft Mesh and it gives users a cross AR/VR meeting space to interact with other users and 3D content, handling all of technical hard parts of sharing spatial multi-player experiences over the web. Like Microsoft’s other AR/VR apps, the sell seems to be less in the software than it is in enabling developers to tap into one more specialization of Azure, building their own software that builds on the capabilities. The company announced that AltspaceVR will now be Mesh-enabled.

In the company’s presentation, they swung for the fences in showcasing potential use cases, bringing in James Cameron, the co-founder of Cirque du Soleil and Pokémon Go developer Niantic.

Virtual reality isn’t just for gaming. Researchers can use virtual reality, or VR, to assess participants’ attention, memory and problem-solving abilities in real world settings. By using VR technology to examine how folks complete daily tasks, like making a grocery list, researchers can better help clinical populations that struggle with executive functioning to manage their everyday lives.

Harvard’s Capasso Group has scaled up the achromatic metalens to 2mm in diameter. That may not sound like much, but it is plenty for virtual reality contact lenses. The human pupil is 7mm at widest. These guys are going to beat Mojo Lens to the finish line for smart contact lenses.
