WebApr 28, 2016 · One can get coherent light from an incoherent source by passing it through a slit, this would give the tiny 1/r^2 fraction of power to be collimated using the laser geometry. The laser in the collimation process does not lose intensity, but gains , because of the lasing action. WebFeb 1, 2024 · This phenomenon is unexpected since spatially coherent illumination is used and the mathematical image reconstruction is based on incoherent superimposing of the intensity. It is anticipated that even under this spatially coherent illumination, the obtained camera image still reserves certain effective information that can be extracted by the ...
