Apple introduced 3D depth sensing technology from the iPhone X, which is the basis of Apple's Face ID function. The iPhone X's 3D camera uses an infrared 3D structured light solution, including "infrared light source + optical components + infrared sensor" and other parts, of which the most critical part is the infrared light source. Early 3D sensing systems generally use LED as the infrared light source, but with the maturity of VCSEL chip technology, in t

2020-11-18

Lithium-ion batteries have developed rapidly in recent years, but because of the constraints of process and production conditions, there is a large contradiction between production capacity and demand, the current lithium battery electrode inspection method is basically a manual visual inspection, however, there is a high probability that there are many defects after the processing of the electrode, all the electrode must be inspected before the battery is

Technical Articles | Introduction to the two forms and types of machine vision interfaces

2020-11-16

Choosing the right interface for your machine vision application is a decisive factor in your camera selection process. The following subsections provide an overview of the different cable and connector types available for machine vision and the associated pros and cons. Machine vision interfaces generally come in two forms: dedicated and consumer. Dedicated interfaces are suitable for very high speed or ultra-high resolution applications where such interfa
