Characteristics and application of linear array camera and area array camera
Release Time: 2023.01.31

In the modern society, the emergence of industrial cameras provides better help for industrial production. According to the structural characteristics of sensors, industrial cameras can be divided into linear array cameras and area array cameras. What are their characteristics and differences? Let's take a look at them.

What is a linear array camera? What is an area array camera?

Linear array camera is a camera using linear array image sensor. It presents a linear image, which is also a two-dimensional image, but it is very long. The length can reach several K, but the width is only a few pixels. Usually, this camera is only used in two cases:

1、 The measured field of vision is a thin and long strip, which is mostly used for detection on the drum.

2、 It requires great vision or high accuracy.

Area array camera is a camera that can acquire images at one time and collect images in time. It has a wide range of applications, such as area, shape, size, position, and even temperature measurement. This camera can quickly and accurately obtain two-dimensional image information, and has a very intuitive measurement image.

Characteristics of linear array camera and area array camera

Linear array camera: special industrial camera has only one line of photosensitive elements, so it can be used in the field of continuous detection with high-speed scanning and high resolution, such as metal, plastic, paper and fiber. The measured object moves at a uniform speed, and can be processed line by line, or form multiple images for processing.

Area array camera: Area array camera can easily read more information, including measuring area, shape, size, position, and even temperature.

Difference between linear array camera and area array camera

Area array camera: widely used, such as area, shape, size, position, and even temperature measurement.

Linear array camera: mainly used in image processing in industrial, medical, scientific research and security fields. Typical applications are to detect continuous materials, such as metal, plastic, paper and fiber. The object to be detected is usually moving at a uniform speed, and one or more cameras are used to continuously scan it line by line to achieve uniform detection of its entire surface. The image can be processed line by line, or the area array image composed of multiple lines can be processed. In addition, the linear array camera is very suitable for measuring occasions, thanks to the high resolution of the sensor, which can accurately measure the micrometer.
