特に光フィードバックによって装置のレンズの焦点距離を調整するための光学装置
Document Type and Number:
Japanese Patent JP7371146
Kind Code:
B2
Abstract:
The invention relates to an optical device, comprising: a lens (10) having an adjustable focal length (f). According to the invention, a light source which is configured to emit light (51) that is affected by said lens (10) and impinges on at least a first photosensitive element (30), which is designed to generate a first output signal (O1) corresponding to the intensity of light impinging on it, wherein the first photosensitive element (30) is configured to measure only a portion of the intensity distribution of said emitted light (51), and wherein the light source (50), the lens (10) and the first photosensitive element (30) are configured such that a change of the focal length (f) of said lens (10) changes the intensity distribution of the emitted light (51) that impinges on the first photosensitive element (30), so that each focal length (f) of the lens (10) is associated to a specific first output signal (01) generated by the first photosensitive element (30). The invention further relates to a corresponding method.
