PROBLEM TO BE SOLVED: To provide a low-cost imaging device having a simple construction.SOLUTION: Provided is an imaging device comprising: an optical coherence tomography equipped with a wavelength sweep light source unit for emitting light and also sweeping the wavelength of the emitted light, an optical system for scanning the light from the wavelength sweep light source unit on a test object and generating an interference signal based on an interference light obtained by combining a reflected light reflected from the test object and a reference light and a control unit for controlling a trigger signal based on the light from the wavelength sweep light source unit and an information processing unit connected to the optical coherence tomography, for processing the interference signal. The control unit determines that the trigger signal is sent to the information processing unit on the basis of information of scan on the test object by the light from the wavelength sweep light source unit, and the information processing unit acquires, upon receiving the trigger signal, information pertaining to the test object from the interference signal, with the trigger signal serving as a point of reference.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】簡単な構成を有する低コストの撮像装置を提供する。【解決手段】光を出射するとともに出射する光の波長を掃引する波長掃引光源部、波長掃引光源部からの光を被検体上で走査し被検体から反射された反射光と参照光とを合波して得た干渉光に基づく干渉信号を生成する光学系、及び波長掃引光源部からの光に基づくトリガ信号を制御する制御部を備える光干渉断層計と、光干渉断層計に接続され、干渉信号を処理する情報処理部とを備え、制御部は、波長掃引光源部からの光の被検体に対する走査情報に基づいて、トリガ信号を情報処理部に送ることを判断し、情報処理部は、トリガ信号を受け取ると、トリガ信号を基準として干渉信号から被検体の情報の取得を行う、撮像装置。【選択図】図3
