Incoherent irradiance

WebIn designing studies to test LLLT hypotheses, there are many parameters that must be considered, including whether to use coherent (laser) or incoherent (LED) radiation, the laser wavelength (or peak wavelength for LEDs), whether to use continuous or pulsed radiation, and the irradiance, target area, and pulse shape. WebMar 16, 2024 · The incoherent irradiance profile rapidly increases approximately 38 cm for C2 and 40 cm for C3 from the entry edge. While a smaller number of scattered rays are absorbed in other regions. This result allows the electric heater positioning in the place as close as possible to that heated by the radiant power.
