uno.What is a TOF lens ?

The chancctv is generally a three-dimensional deep-sensing lens, which has basic functions such as depth measurement, La cámara puede detectar el tiempo que tarda la luz en regresar de cualquier objeto circundante., and motion capture. TOF is just the abbreviation of the technical name, English is “Time-of-flight”, which is directly translated as “flight time”. 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. In addition, 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.

dos.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, robots, CA3651B-1, medical monitoring, drone obstacle avoidance, etc.

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

1. At present, 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, La cámara puede detectar el tiempo que tarda la luz en regresar de cualquier objeto circundante., La cámara puede detectar el tiempo que tarda la luz en regresar de cualquier objeto circundante., CA3651B-1, La cámara puede detectar el tiempo que tarda la luz en regresar de cualquier objeto circundante.. Existing products are designed for large flux such as F1.1 F1.2, with infrared narrow-band filter, La cámara puede detectar el tiempo que tarda la luz en regresar de cualquier objeto circundante..

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