CCD image sensors (charge coupled device) are electronic devices that are capable of transforming a light pattern (image) into an electric charge pattern (an electronic image). The CCD consists of several individual elements that have the capability of collecting, storing and transporting electrical charge from one element to another. This together with the photosensitive properties of silicon, is used to design image sensors. Each photosensitive element will then represent a picture...

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of CCD image sensors?
10 answers
Answers:
Before purchasing a device with CCD sensor do enough research what applications you may need your device for. Later upgrades can be costly.
~Ivica M, Technical Support, Zagreb, Croatia
Trial at least for 6 months before duplicated, selection of colour/ monochrome depending upon the application requirement.
~MN Krishnamurthy, Engineer, Bangalor, India
Define your need before you select CCD image sensor; signal to noise needs, transfer rate or required frame rate.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using CCD image sensors?
9 answers
Answers:
To be tested for reliability before procurement and duplication, consideration of flexibility for the user for handling the system to be considered and training impartation for the users.
~MN Krishnamurthy, Engineer, Bangalor, India
CMOS sensors are not cheap compared to CCD as CMOS imager technologies tend to become specialized. Time integrated delay can not be easily done by standard CMOS technologies.
~Yann H, Research & Development, Grenoble, FRANCE
Define your needs and then: 1. compare cost per value 2. CMOS Vs. CCD pro. and con. for your application
~Shmuel Matis, Engineering Consultant, Rehovoth, Israel
Chose the CCD sensor that provides best price/features-quality ratio.
~Ivica M, Technical Support, Zagreb, Croatia
Read your highly informative magazine and do the research.
~John D, Research & Development, Denny, Uk
They have to chooe related with their needs.
~Zuhtu C, Architect, Antalya, TURKEY
Study and use the product before purchasing.
~Roland E, Manager, Charlotte, NC
Specify clearly what you need.
~Harald Michaelis, Research & Development, Berlin, Germany
Read about it before.
~Engineer, The hague, Netherland
