This invention discloses a slag volumetric flow rate measuring device and method. The slag volumetric flow rate measuring device includes: a binocular camera, with one camera on each side of the center of the slag discharge direction, and the two cameras arranged front and back in the slag discharge direction; a green laser source for emitting green laser lines; a red laser source for emitting red laser lines; one of the red and green laser lines is parallel to the slag discharge direction, and the other is perpendicular to the slag discharge direction; each camera of the binocular camera acquires a slag discharge image simultaneously displaying both green and red laser lines. This invention's measuring device uses two lasers (red and green) and a binocular camera. The cross-sectional area of ​​the slag on the conveyor belt is calculated using the R-channel image, and the displacement is calculated by cross-correlation using the matching results of two consecutive frames of the G-channel image. The conveyor belt speed is calculated by combining the sampling time, and the cross-sectional area and speed are coupled to achieve online detection of slag volumetric flow rate.

This invention provides a light source for projectors that can broaden the color gamut of projected images and improve color reproduction. [Solution] The spectroscopic element 4 spectrally separates the red laser light R, green laser light G, and blue laser light B emitted from the red laser light source 1R, green laser light source 1G, and blue laser light source 1B, respectively, and emits them in different directions. The diffusion member 62 is formed in one region of the base member 61 and diffuses and reflects the incident red laser light R and green laser light G. The fluorescent / diffusing member 63 is formed in another region of the base member 61 and includes a phosphor that is excited by a portion of the incident blue laser light B to emit yellow light Y, and a diffusion material that diffuses and reflects the other portion of the blue laser light B. The focusing element 5 mixes the red laser light R and green laser light G reflected by the diffusion member 62, the yellow light Y emitted from the fluorescent / diffusing member 63, and the blue laser light B reflected by the fluorescent / diffusing member 63 and emits it as white light W.
