In the bright and tidy inspection room, an experienced worker is fully engrossed in the inspection of quartz crystals. He is dressed in a neat work uniform, wearing professional protective gloves and goggles. On the workbench in front of him are a series of precision testing instruments and samples of quartz crystals awaiting inspection. He carefully picks up a quartz crystal, gently places it on the stage of a high-precision microscope, and then skillfully adjusts the focus and angle of the microscope. His eyes are fixed intently on the eyepiece as he closely observes the microscopic structure inside the crystal. His gaze is sharp and focused, not missing any subtle features. From time to time, he rotates the crystal in his hand to examine its unique lattice arrangement from various directions.

When identifying the crystal orientation, relying on his profound professional knowledge and years of accumulated practical experience, he accurately determines the crystal orientation of the quartz crystal by observing the changes in the optical properties of the crystal under specific lighting conditions and making a meticulous comparison with the standard crystal orientation atlas. Every movement of his is precise and steady, and every observation is meticulous. The whole process is filled with a rigorous attitude towards work and a persistent pursuit of technology. It seems that in his world, at this moment, there is only the quartz crystal in front of him and the crystal orientation that urgently needs to be determined accurately.
