What is optronic technology?
Optronic technology is a gas detection solution and is gaining popularity in various sectors. Optronics is increasingly used in mining, defense, aviation, biogas production, marine, oil and gas plants and entertainment.
The military is also a significant beneficiary as dircm defense optronics become popular because of highly robust detectors and reliable gas detection even in harsh weather conditions such as sandstorms.
Optronic technology and cameras
Technology has also transformed photography. There are several factors to consider when purchasing a vision camera. The features to bear in mind are
- Camera applications
- Inspection spectrum
- Image sensors
- Communication interphase
First, decide the kind of camera application that suits your needs. For instance, if you want a camera for robotics guidance, buying a camera for production control may not give you the desired effect.
Secondly, decide the inspection spectrum viable with your application. Your desired images can only succeed if you match them with the appropriate application. Some of the common spectra are ultraviolet and infrared visions.
The sensor is also a critical factor to consider. The most preferred camera sensors are CMOS, FPA, and CCD.
The last and most critical factor that completes your choice is the interface. Purchase an appropriate communication interface such as Camera Link and USB 2 OR 3.0.
You must synchronize your intended image results with the camera’s vision. Your priority defines the objective of the inspection. It also determines the best radiation that gives the kind of information you need.
Radiation is critical because it determines the camera’s inspection spectrum. For instance, a broad view is necessary if you are using it for process supervision. However, a narrow infrared scope is acceptable for a furnace camera.
Types of cameras observation spectra
There are different types of camera observation spectra. These are those sensitive to
- visible elements
- thermal vision or infrared
How many megapixels is fit for your need?
The sensitivity of the camera determines the quality of images you get. A very sensitive camera produces clear images, even when the light amount is unreliable. Exceptional image quality is the product of the camera’s sensitivity and picture resolution.
Therefore, more megapixels produce incredibly sharp images and very definite photos. When you are interested in the details in a target image in focus, use a camera with a resolution above 1 megapixel or go for H.264 form.
The market has many and affordable megapixels. You can purchase several to meet the various needs of your projects.
Applications for a camera vision machine
Camera vision machines have become the preferred choice for production control, surface inspection and flow management. They are also ideal for robotic applications and electronic manufacturing. Generally, there is a most definite camera for each application.
For instance, FPA is the most preferred application for medical imaging because it gives precise results. On the other hand, a microbolometer camera is the best suited for identifying and measuring heat flow.
The camera sensor is the defining factor in photography. A camera can have weak sensitivity, reliably good resolution but producing poor images.
On the other hand, some cameras require high sensitivity to produce sharp visible images even in poor lighting. High-quality images can also be obtained with average resolution. However, the risk is interference from thermal noise because of highly sensitive sensors.
The lenses must operate at maximum aperture, optimum optical quality and reasonable focal length. All these factors contribute to the quality of the image formed in the camera’s sensor.
What about smart cameras?
A smart camera can process and interpret images.
Advantages of smart cameras
A smart camera does not need a cable connection to process images. Instead, it interprets the images using an in-built processor.
Once a smart camera interprets an image, it can control all its operations and monitor accurate integrated image processing. A smart camera has an embedded image interpretation unit. It avoids the need to have an independent image interpreting reader.
A smart camera is designed to have automatic operations. Therefore, all its commands are digitized, making it easy to use or learn.
A digital camera has a very simplified installation and requires minimal space when in use. It also fits in a small camera pocket for ease when on transit.
Choosing a camera and matching it with the most appropriate features, gives unmatched, high-quality images. Consult a professional to help you purchase a camera that meets your needs.
