1つ.What is a TOF lens ?

The TOFレンズ is generally a three-dimensional deep-sensing lens, 深度測定などの基本機能を搭載, 骨認識, とモーションキャプチャー. TOFは単に技術名の略です, 英語は “飛行時間”, として直接翻訳されます “飛行時間”. The sensor emits modulated near-infrared light, normally IR850 ± 10nm @ T> 90%, FWHM = 40 ± 5nm, 350-1100nm @ T <1%, When reflecting after encountering an object, the sensor calculates the time difference or phase difference of light emission and reflection to convert the distance of the scene to be shot to generate depth information. 加えて, combined with traditional camera shooting, the three-dimensional outline of the object can be represented in different colors to represent the topographic map of different distances.

二.TOF lens main application industry

TOF brings revolutionary changes to machine vision. The effective depth information point of TOF reaches 300,000. After obtaining the 3D model through the depth information, it can be applied to many industries. Such as autonomous driving, ロボット, 自動化装置, medical monitoring, drone obstacle avoidance, NS.

三.TOF lens major manufacturers and Chuangan Optics TOF lens layout

1. 現在のところ, TOF lenses of Sunny Optical and United Optoelectronics are mainly used in mobile phones and other fields.

2. The layout of Chuangan Optics on the TOF lens is mainly used in the non-mobile phone industry. Chuangan Optics has carried out preliminary design and production on TOF lenses, 主に深さ測定に使用されます, 骨認識, モーションキャプチャ, そして自動運転. Existing products are designed for large flux such as F1.1 F1.2, with infrared narrow-band filter, IR850nmやIR940nmなど.

It is understood that the TOF lens models currently in mass production are as follows
