GRAIN ANGLE SENSOR

摘要

A grain angle sensor system (40) for measuring grain angle direction of surface fibers of a wood object (26) with respect to at least one of a surface plane direction or a transverse direction, such as a dive angle, or with respect to both the surface plane and transverse direction. The system (40) includes multiple laser diodes (44) and photosensor detectors (52) integrated into an electro-optical assembly (54) that can sequence the firing of the lasers (44) to minimize crosstalk. An exemplary assembly (54) includes an enclosure housing an electronic control board connected to circuit cards containing multiple laser diodes (44) and multiple photosensor detectors (52).
