Title (EN) ENDOSCOPE LIGHT SOURCE DEVICE AND ENDOSCOPE SYSTEM
(FR) DISPOSITIF DE SOURCE DE LUMIÈRE POUR ENDOSCOPE ET SYSTÈME D'ENDOSCOPE
(JA) 内視鏡用光源装置及び内視鏡システム
Abstract:
(EN) This light source device comprises: a first optical element which generates transmitted light obtained by removing a first wavelength band component from incident light, and generates reflected light obtained by extracting the first wavelength band component from the incident light; a first light source which emits light including at least the first wavelength band component, and causes said light to be incident on the first optical element in such a way as to become the reflected light of the first optical element; a second light source which emits light in such a way that light including a wide second wavelength band component that includes the first wavelength band becomes the transmitted light of the first optical element; and a control unit which controls the drive of the first light source and the second light source. The control unit selectively emits the first light and the second light by controlling the turning on/off of the emission of the first light source emitted light and the emission of the second light source emitted light.
(FR) Cette invention concerne un dispositif de source de lumière comprenant : un premier élément optique qui génère la lumière transmise obtenue par soustraction d'une première composante de bande de longueur d'onde de la lumière incidente, et qui génère la lumière réfléchie obtenue par extraction de la première composante de bande de longueur d'onde de la lumière incidente ; une première source de lumière qui émet une lumière contenant au moins la première composante de bande de longueur d'onde, et amène ladite lumière à être incidente sur le premier élément optique de façon à devenir la lumière réfléchie du premier élément optique ; une seconde source de lumière qui émet une lumière de façon que la lumière contienne une large seconde composante de bande de longueur d'onde qui contient la première bande de longueur d'onde qui devient la lumière transmise du premier élément optique ; et une unité de commande qui commande l'excitation de la première source de lumière et de la seconde source de lumière. L'unité de commande émet sélectivement la première lumière et la seconde lumière par commande de la mise sous/hors tension de l'émission de la lumière émise de la première source de lumière et de l'émission de la lumière émise de la seconde source de lumière.
(JA) 光源装置は、入射光から、第1波長帯域の成分を除去した透過光と入射光から第1波長帯域の成分を抽出した反射光を生成する第1光学素子と、前記第1波長帯域の成分を少なくとも含む光を出射し、前記第1光学素子の反射光となるように前記第1光学素子に入射させる第1光源と、前記第1波長帯域を含む広い第2波長帯域の成分を含む光が前記第1光学素子の透過光となるように光を出射する第2光源と、前記第1光源及び前記第2光源の駆動を制御する制御部と、を有する。前記制御部は、前記第1光源出射光の出射と前記第2光源出射光の出射のオン/オフを制御することにより、前記第1の光の出射及び前記第2の光の出射を選択的に行う。
