Abstract
Embodiments include techniques for determining the uniformity of a powder layer distribution, where the techniques include pre-heating a powder layer, scanning the powder layer, and receiving a signal from the powder layer. The techniques also include filtering the received signal, measuring a radiation intensity of the received signal over a range of wavelengths, and comparing the measured radiation intensity to a reference spectrum for the powder layer.
