(JA) 光学装置
Abstract:
(EN) Provided is an optical apparatus with which it is possible to suppress the reception of light having a wavelength outside of reflected light. This optical apparatus (1) has: a light source (2) in which it is possible to change the wavelength of laser light; a scanning unit (5) that diffracts the laser light in accordance with the wavelength thereof, thereby scanning a prescribed range; and a wavelength control unit (9) that changes the wavelength of the laser light, thereby scanning the prescribed range using the laser light via the scanning unit (5). Furthermore, the optical apparatus has: a light-receiving element (8) that receives reflected light obtained by the scanned laser light being reflected by an object (100); and an FP filter (6) that changes the wavelength of transmitted light, thereby preventing the light-receiving element (8) from receiving at least some of environmental light that is oriented toward the light-receiving element (8) via the scanning unit (5).
(FR) L'invention concerne un appareil optique avec lequel il est possible de supprimer la réception de lumière ayant une longueur d'onde à l'extérieur de la lumière réfléchie. Cet appareil optique (1) comprend : une source de lumière (2) dans laquelle il est possible de modifier la longueur d'onde de la lumière laser ; une unité de balayage (5) qui diffracte la lumière laser en fonction de sa longueur d'onde, ce qui permet de balayer une plage prescrite ; et une unité de commande de longueur d'onde (9) qui modifie la longueur d'onde de la lumière laser, balayant ainsi la plage prescrite à l'aide de la lumière laser par l'intermédiaire de l'unité de balayage (5). En outre, l'appareil optique comprend : un élément de réception de lumière (8) qui reçoit la lumière réfléchie obtenue par la lumière laser balayée qui est réfléchie par un objet (100) ; et un filtre FP (6) qui modifie la longueur d'onde de la lumière transmise, ce qui empêche l'élément de réception de lumière (8) de recevoir au moins une partie de la lumière ambiante qui est orientée vers l'élément de réception de lumière (8) par l'intermédiaire de l'unité de balayage (5).
(JA) 反射光以外の波長の光の受光を抑制することができる光学装置を提供する。光学装置(1)は、レーザ光の波長を変化させることができる光源(2)と、レーザ光をその波長に応じて回折させることで所定の範囲を走査する走査部(5)と、レーザ光の波長を変化させることで、走査部(5)を介してレーザ光で所定の範囲を走査させる波長制御部(9)と、を有している。さらに、走査されたレーザ光が対象物(100)で反射した反射光を受光する受光素子(8)と、透過させる光の波長を変化させることで、走査部(5)を介して受光素子(8)へ向かう環境光の少なくとも一部を受光素子(8)に受光させないFPフィルタ(6)と、を有している。
