Description:

CCD lenses

Magnagon lenses for chargecoupled devices (CCDs) are used in image processing applications to meet demand for high imaging quality. The lenses show very low flare, low chromatic aberration, and are free of vignetting for the entire magnification scale.

The machine vision detection system uses CCD camera to convert the detected object into image signal and transmit it to special image processing system. According to the information of pixel distribution, brightness and color, it is transformed into digital signal. The image processing system performs various operations on these signals to extract the characteristics of the target, such as area, quantity, position and length, and then according to the preset allowable degree and its The output results of other conditions, including dimensions, angles, number of items, qualified / unqualified, yes / no, etc., can realize automatic identification function.

Features:

1.Imaging process

CCD is transferred by frame or line under the coordination of synchronous signal and clock signal. The whole circuit is very complex and the readout rate is slow

2.Integration

It is difficult to integrate a / D conversion, signal processing, automatic gain control, precision amplification and storage functions into a single chip because of the complexity of CCD readout circuit with special manufacturing process. Generally, it needs multiple chip combination to realize, and also needs a multi-channel non-standard power supply voltage. With the help of large scale integrated manufacturing process

3.Power and volume

CCD needs a variety of power supply, power consumption is large, the volume is relatively large.

4.Performance index

CCD technology is quite mature

Application:

CCD VISUAL MARKING

What is a CCD in a camera?

A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging
