The specificity of the laser emission principle and the production process determines that the laser has the characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, good directivity) and high (high brightness).
Making an electronic pointer pen: The teacher uses laser projection points to remind students to observe and think.
Electronic level: Let the motor drive the bald head to rotate or twist, and project it into a straight line on the wall for reference when decorating or posting New Year pictures.
Miniature LCD projection: Remove the condenser lens and let the laser pass through the controllable LCD screen to produce a clear projection on the wall.
Long-distance laser monitor: Let the laser shine on the glass of the room being eavesdropped on, and then receive the laser beam reflected from the glass, and detect the vibration of the glass to restore the sound of the room.
Long-distance light-controlled anti-theft alarm: Install a laser emitting tube and a photoresistor at one corner of the fish pond or watermelon field that needs to be protected, and install a mirror at the other three corners to form a protection zone.
Long-distance laser wireless communication: Use a pair of laser transceivers to face each other on two remote roofs, and use the serial communication protocol of the single-chip microcomputer to send and receive files, and even network.
