Optical radiation meaning
Web• Spectroradiometric flux (watts/ nm): Generally, optical radiation refers to that slice of the electromagnetic spectrum from about 200 nm to 20 µm. The spectrum of a particular light source is represented by its spectral density, in units of power per wavelength interval. Figure 2 shows the typical spectral densities of two common light sources. WebSep 13, 2024 · Optical data captured in an optical system may be distorted or otherwise affected by various factors, such as but not limited to physical interference, fluorescence, noise or other factors. The effects on the optical data may interfere with any number of uses of the optical data, such as identification, presentation, or the like. Although various …
