Description
This Speed of Light Measurement Apparatus supports two measurement methods: the phase method and the Lissajous figure method. The instrument is 0.8 meters long, and the optical path can be adjusted from 0 to 1 meter. The phase shift range is -180° to +180°. Using the Lissajous method, students can clearly observe patterns at phase angles of 0°, 45°, 90°, 135°, and 180°. The resolution is 0.2 mm. The modulation frequency is 150 MHz, and the phase detection frequency is 455 kHz. This apparatus helps students understand modern optics concepts.
Seven Learning Tasks
This Speed of Light Measurement Apparatus enables students to complete seven experimental tasks. First, they measure the speed of light using either the phase method or the Lissajous method. Second, they determine the modulation wavelength. Third, they use the frequency difference method for phase measurement. Fourth, they study the basic principles of optical modulation. Fifth, they learn calibration and operation of an oscilloscope. Sixth, the system includes an analog communication interface, allowing optional laser communication experiments. Seventh, a transparent rod can be added to measure the refractive index or the speed of light in a medium. This system is well-suited for comprehensive university laboratory teaching.
Precision Rails and Low Power Consumption
The apparatus features a precision rail for the phase shifter, with a length of 600 mm. The flatness and parallelism are both controlled within 0.02 mm, ensuring high precision. The system includes one receiving channel, one frequency measurement channel, one reference channel, and one modulation channel. Power consumption is only 8 W. Measurement accuracy is ≤3%, and waveform amplitude variation is ≤1%. The prism carriage can be adjusted vertically. The minimum order quantity is one unit, and samples can be provided before bulk orders (free samples are not available). This apparatus is widely used in educational institutions.
