Which frequency is associated with the LIDAR technology?

• A. 10.525 GHz
• B. 330 THz
• C. 24.15 GHz
• D. 33.4 GHz

Answer: (B)

The correct choice pertains to a frequency of 330 THz, which is associated with LIDAR technology due to its operation in the optical spectrum. LIDAR, which stands for Light Detection and Ranging, uses light in the form of a pulsed laser – often in the infrared and near-infrared wavelengths. The frequency range for visible and near-infrared light is significantly higher compared to microwave frequencies, placing it in the terahertz range.

The 330 THz frequency corresponds closely to the optical wavelengths of light, which is instrumental in LIDAR's functionality for measuring distances based on the time it takes for the emitted light to reflect off an object and return to the sensor. This rapid pulse and high frequency allow for precise measurements and high-resolution imaging, making LIDAR a powerful tool in various applications including mapping, autonomous vehicles, and surveying.

In contrast, the other frequencies listed—10.525 GHz, 24.15 GHz, and 33.4 GHz—are indicative of microwave radar technology rather than the optical laser technology used in LIDAR. These frequencies do not allow for the same level of precision and detail that LIDAR achieves with its operation in the optical spectrum.
