Multi-part mirror for focusing diffuse light

Mechanical Engineering Journal, 2017
In the present study a multi-part mirror is developed for focusing only a scattered light effectively. The multipart mirror is composed from several elliptic mirrors. Several elliptic mirrors are installed on the surface of the multi-part mirror. Primary

Spectral-Free Double Light Detection of DNA Based on a Porous Silicon Bragg Mirror

Sensors, 2022
To improve the detection sensitivity of a porous silicon optical biosensor in the real-time detection of biomolecules, a non-spectral porous silicon optical biosensor technology, based on dual-signal light detection, is proposed.

A Thermal-Solar System for De-Orbiting of Space Debris [PDF]

INCAS Bulletin, 2018
This paper presents a system for removal of space debris, which can be placed on geocentric, heliocentric or Sun-synchronous orbit. The system is composed of two parabolic mirrors, a large one and a small one.

A representative dataset of the self-reproducing light ray family between the multiple distributed Bragg reflectors of multiple VCSELs and the inner surface of plane-convex mirror

Data in Brief, 2021
A system consisting of a plano-convex mirror and reflecting surfaces of Vertical Cavity Surface-Emitting Laser (VCSEL) Strip Array of Diode Lasers has been calculated and proved to have a self-reproducing ray sink in it.

Mirror-induced reflection in the frequency domain

, 2022
Mirrors are ubiquitous in optics and are used to control the propagation of optical signals in space. Here we propose and demonstrate frequency domain mirrors that provide reflections of the optical energy in a frequency synthetic dimension, using ...
