Sun-sensing systems are used for coarse attitude acquisition and Sun vector estimation. These units typically use quadrant photodiodes or linear arrays, positioned behind pinholes or refractive optics ...

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

Although optical subsystems are widespread in applications such as sensing and telecoms today, the way in which the optics components are assembled and packaged remains a tricky and time-consuming ...
