Tech/Engineering - Electronics / Elect Eng | | English term or phrase: Relative emission intensity (a. u.) | I'm wondering about the right meaning / French abbreviation for "a.u." in this context (LED emitter).
The sole thing I found for this is Angstroem, which doesn't really fit in here
Thx by advance |
| | | arbitrary units | Explanation:
In science and technology, an arbitrary unit (abbreviated arb. unit) or procedure defined unit (p.d.u.) is a relative unit of measurement to show the ratio of amount of substance, intensity, or other quantities, to a predetermined reference measurement.

enhancement in LEDs
Fig. 3. Simulated far-field emission pattern at a wavelength of 870 nm.
(a) Planar LED without grating on top, which shows a Lambertian pattern.
(b) LED with a periodic a-Si / air grating of optimized parameters (Λ = 500 nm and t = 200 nm), which shows a non-Lambertian pattern.
(c) Averaged angular dependence of light emission for devices without (green) and with (red) a-Si grating. The normalized intensity has an arbitrary unit."
