portable laryngeal stroboscope by LED light source

摘要

The present invention relates to a laryngeal stroboscope with LED as light source, the imaging unit and particularly the front end Laryngeal endoscopy and is equipped with LED light source; It is connected to the endoscopic laryngeal, voice signal detection unit configured to detect a speech signal; And an audio signal receiving unit which receives the audio signal measured by the voice signal detecting unit; Comprise; and according to the audio signals received by the audio signal receiving unit such that the LED light source is interrupted, the image signal photographed by the imaging unit according to whether or not the intermittent control of the LED light source to appear on a video display unit and to use the LED as the light source, it characterized in that the portable larynx stroboscopic a technical base. This extracts the audio signal in response, there is an advantage to implement a strobe effect intermittent light of the LED light source to a predetermined number of times according to the speech signal can be clearly observed the behavior of the vocal cords.
