The MIT team suggested that the BeC radioactive atoms, the Rubidium-83-radioactively decompose synchronized to get a laser beam. The neutrinos are naturally released during radioactive decay, and in the quantum state of the Bec, that decay should accelerate, the effect that should create an enhanced neutrino beam, is akin to how stimulated radiation enhances photons to obtain an ordinary laser beam. The next step is to create a desktop demonstration of the concept. If this works, the team involves the use of neutrino lasers as a new tool for underground communication and as a source of radioisotopes for medical visualization and cancer diagnosis.

Pinhole camera restoration for IR visualization

The earliest forms of the Pinhole camera have existed for millennia, dated even before the 4th century BC in China. The light passes through a tiny hole, broken into a light -resistant box, projecting an inverted image of the scene from the outside on the opposite of the inner wall. Visualization based on lenses is subject to distortion and has restrictions on the depth of the field and wavelength. Thus, scientists have revived Pinhole technology to create a prototypical camera for infrared visualization. paper Published in Optica magazine.
To create their own image system with IR-handrails, the authors used a laser to create an optical hole inside a non-linear crystal with a “chirplen” structure capable of collecting light rays from a wide range of directions, which leads to a wider field of view. The unique optical properties of the crystal essentially transform infrared images into visible light, which allows the standard silicon chamber to record these images. The process also naturally suppresses noise, so it can work even in low light conditions.
To check their prototype, the team used IR images with a 3D foal for depicting a matte ceramic rabbit and reconstructing their three-dimensional shape, synchronizing ultra-suffering pulses. IR camera with plugs can even be adapted to long-infrared or terager wavelengths. This is still a lot at the stage of confirmation of the concept, but as soon as their innovations make IR systems of images more affordable, portable and energy-efficient, the authors represent applications in night vision, industrial quality control and environmental monitoring, and otherwise.
