(5.6s) Hi, I'm Nick Sischka, an imaging engineer at Edmund Optics. One of the most common questions that I get as an imaging engineer is how can I increase my depth of field or how can I maximize the depth of field of my system?

And unfortunately, in a traditional lens system, the depth of field is limited by the aperture size and by the resolution of the lens system that you are using. However, with the advent of some new technology, namely liquid lens technology or focus-tunable lens technology, one is able to very rapidly refocus between different heights of objects and overcome the limitations of depth of field. For example, if you're looking at two different objects that have two different heights, you can very, very quickly refocus from one plane of focus to the next on the order of tens of milliseconds. The system here has two different imaging systems set up, both with a 25 millimeter focal length lens. However, the system on the left is augmented with a focus tunable lens. And as the jars spin by and are triggered, the focus tunable lens is able to focus very quickly on each height of the jar. The system on the right, however, which does not have a liquid lens on it, is only able to focus on one plane at a time. Thanks so much for joining me. And again, I'm Nick Sischka, an imaging engineer at Edmund Optics. (10.5s)

液体レンズ技術の理解

液体レンズは、ピントの素早い調整を必要とする広範なアプリケーションに対して、画像システムの柔軟性を最大化するのに用いることができます。液体レンズを実装することで、画像システムは焦点面を数ミリ秒で変えることができ、カメラからの物体距離に依存せずにシャープな画像を作り出します。液体レンズの実装は、バーコードリーダーや包装選別、セキュリティ、迅速なオートメーション化など、検査対象物のサイズやレンズからの距離が異なったりする場合に、複数の地点にピントを合わせる必要のあるアプリケーションに理想的選択となります。本技術に関する更なる情報は、Liquid Lens Technologyをご覧ください。
