What is the principle and application of TOF lenses? What are the manufacturers of TOF lenses? What are the prices of TOF lenses?

一.What is a TOF lens ? The TOF lens is generally a three-dimensional deep-sensing lens, which has basic functions such as depth measurement, bone recognition, 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 [...]

What’s a mirrorless camera and what makes it different from a DSLR?

As the name suggests, a mirrorless camera is one that doesn’t require a reflex mirror, a key component of DSLR cameras. The mirror in a DSLR reflects the light up to the optical viewfinder. In a mirrorless camera, there is no optical viewfinder. Instead, the imaging sensor is exposed to light at all times. This gives you a digital preview of your image either on the rear LCD screen or an electronic viewfinder (EVF). Mirrorless cameras are called “mirrorless,” rather than [...]

What changes will 5G bring about in security industry?

NGMN defines 5G in this way: 5G is an end-to-end ecosystem that will create a fully mobile and fully connected society. 5G mainly includes three aspects: ecology, customer and business model. It offers a consistent service experience that creates value for customers and partners through existing and new cases and sustainable business models. As an important scene of 5G application, intelligent security will bring about what kind of changes in security ecology and business model, which is worthy of our expectation and [...]

What is DOF?

In optics, particularly as it relates to film and photography, the optical phenomenon known as depth of field (DOF), is the distance about the plane of focus (POF) where objects appear acceptably sharp in an image. Although an optical imaging system can precisely focus on only one plane at a time, the decrease in sharpness is gradual on each side of the POF, so that within the DOF the unsharpness is imperceptible under normal viewing conditions. In some cases, it may be desirable to have [...]
