Analysis of the Technical Principles of Infrared Simultaneous Interpretation Systems


Infrared simultaneous interpretation systems overview


In the vigorous development of modern conference technology, infrared simultaneous interpretation system has become an indispensable key component. This system uses infrared technology for multi-channel voice transmission, located between visible light and microwaves in the electromagnetic spectrum. In the field of conference systems, infrared simultaneous interpretation systems are widely used in simultaneous interpretation and discussion systems, providing efficient and secure voice transmission solutions for conferences with their unique working principles and technical characteristics.

Working principle of infrared simultaneous interpretation systems


The working principle of the infrared simultaneous interpretation systems are based on the physical characteristics of infrared rays. Specifically, the system uses infrared rays in the near-infrared region, with a wavelength of about 850nm-900nm and a modulation frequency generally lower than 10 megahertz. This infrared light is mainly emitted by the infrared transmitter, and adjusts the strength of the infrared light according to the information characteristics, while the receiver uses a photodiode to receive the infrared light and convert it into an information-carrying electrical signal. This process realizes multi-channel voice transmission, providing an efficient working mechanism for simultaneous interpretation and discussion systems.


Analysis of characteristics of infrared simultaneous interpretation systems


Confidentiality and physical characteristics


Based on the physical characteristics of infrared rays, the infrared simultaneous interpretation system has certain advantages in terms of confidentiality. Through physical means such as light shielding and building partitions, the system can achieve basic confidentiality requirements. However, to achieve true confidentiality, the system not only relies on basic physical means, but also needs to rely on coding and decoding technology in data transmission and corresponding data encryption technology. The mainstream all-digital infrared simultaneous transmission systems in the industry currently use coding and decoding technology to achieve confidentiality, while the application of data encryption is relatively limited.


Flexibility and applicability


The applicability of the infrared simultaneous interpretation system is mainly concentrated in small and medium-sized indoor conference applications. Due to the shorter wavelength of infrared rays, they are sensitive to interference from sunlight and high-frequency light sources, and their wavelength characteristics determine poor diffraction ability, only able to achieve line-of-sight transmission. Although infrared rays have a certain reflection ability, their auxiliary effect is limited. Therefore, in indoor environments, especially small and medium-sized conference scenarios, the infrared simultaneous interpretation system exhibits good flexibility and reliability.


The infrared simultaneous interpretation system plays an important role in modern conference systems with its unique working principles and technical characteristics. By fully utilizing the physical characteristics of infrared rays, the system achieves efficient and secure voice transmission, meeting the requirements of simultaneous interpretation and discussion systems for confidentiality and reliability. However, its applicability is still limited by the wavelength characteristics, and it performs well in small and medium-sized indoor conference scenarios. The continuous innovation and development of infrared simultaneous interpretation systems will undoubtedly provide a broader space for the advancement of future conference technology.
