In the field of signal processing and communication, the combination of "heterodyne detection" and "heterodyne detection" has become essential for various applications. Heterodyne detection involves mixing an incoming signal with a local oscillator frequency to produce a new signal with a lower frequency, making it easier to process and analyze. This technique is widely used in radar systems, wireless communication, and optical communication. Example sentences: 1. The use of heterodyne detection in optical microscopy greatly improved the resolution of the images. 2. Heterodyne detection is essential for measuring the frequency of radio signals in high-frequency communication systems. 3. The accuracy of external interferometer can be greatly improved by using heterodyne detection. These examples showcase the versatility and significance of "heterodyne detection" in modern technological advancements.
