Scope

This document describes the methods for testing the luminance and chromaticity performance of laser light source modules in laser display devices and light source components. The light source module includes one or more laser devices and an optical output device, covering a wavelength range of 380 nm to 780 nm. The laser devices contain one or more laser-generating devices, such as edge-emitting laser diodes (LD), vertical cavity surface-emitting laser diodes (VCSEL), or laser devices that convert photons through second-harmonic generation (SHG). The optical output device includes optical waveguides, compound lenses, lenses, and other spatial output devices, or waveguide output devices such as optical fibers, which are used to collect the output of multiple laser devices and emit a beam of laser light.
Note: See the definition of laser devices in Section 3.1.5.
