The path of light

This exhibit the phenomenon of optical reflection to visitors through interactive experiences. The exhibit mainly consists of optical components (flat mirrors), photoelectric sensors, knobs, buttons, light boxes, etc. After visitors press the "start" button, the transmitter at the starting point will emit laser light. Turning the knob of the corresponding color can control the rotation of the plane mirror, causing the laser beam to change its propagation direction through mirror reflection. When the beam hits the top target center, the target center sensor detects the beam and triggers a sound. At the same time, the light box lights up, visually presenting the wonderful effect of optical reflection. one Press the "Start" button in the corresponding area of the exhibit to activate the laser emitter 2 Rotate the knob to control the rotation of the plane mirror to adjust the direction of beam reflection, so that the laser beam accurately hits the top target center. Reflection application principle: The plane mirror in the exhibit is the core optical reflection element. When the laser beam is irradiated on the surface of the plane mirror, reflection occurs. By rotating the knob to change the angle of the plane mirror, the propagation direction of the reflected light can be adjusted.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
