Reflector array
WebThe back reflector (see Figures 1 and 2 below), which is on the side of the array where the ionizing radiation enters, ensures no light is emitted away from the detectors. Selecting an array reflector material balances the structural integrity of the material and its reflection and isolation properties. WebIn combination with a reflector, the Reflex Array MultiTask photoelectric sensor detects leading edges of small, flat, transparent or unevenly formed objects on conveyor belts …

WebA reflector array includes a support structure, a motor, a shaft operatively coupled to the motor, a free plate, and a drive plate. The free plate includes a free plate first side and a free plate second side axially opposed to the free plate first side. The free plate further may include a latching mechanism disposed on the free plate second side and a drive plate. WebThese rovers were equipped with small retroreflector arrays each consisting of 14 corner cubes of triangular configuration (not cut into a circle—imagine slicing off the corner of a cube with a knife). Each reflector is 11 cm on a …
A reflectarray antenna (or just reflectarray) consists of an array of unit cells, illuminated by a feeding antenna (source of electromagnetic waves). The feeding antenna is usually a horn. The unit cells are usually backed by a ground plane, and the incident wave reflects off them towards the direction of the … See more It is important to analyse the reflection magnitude $${\displaystyle S_{11} }$$ and the reflection phase $${\displaystyle \angle S_{11}}$$ across the frequency bandwidth of operation.
