Second-order Coherence Effects Due to the Superposition of Two Independent Thermal Light Beams |
|
| Abstract: | A photon-coincidence counting technique has been used to observe the second-order coherence in a plane receiving light from two small incoherently illuminated apertures. Measurements made for two wavelengths, 546·1 and 435·8 nm, gave results consistent with predictions from the van Cittert-Zernike theorem. |
