Before you start choosing the MTF testing services that you wanted to hire, it is very important that you feed yourself a lot of information about the modulation transfer function and how it characterizes the performance of the imaging system.

What is modulation transfer function?

The quality of an image when it comes to the vision system is the measurement of how you can extract the information easily from the resulting image that you have. The image quality is now quantified through the resolution because it is the measurement of the details of the object that can be detected using the system. To put it simply, the lenses with high quality has the ability in transferring more contrast even at high frequencies compared to lenses with poor qualities.

Therefore, the capability of the imaging system in transferring the contrast of the object at a certain frequency level is often quantified using the modulation transfer function. For instance, if the object has 1005 of contrast, then the modulation transfer function will serve as the plot of the contrast of the image versus the frequency of the object. Now, the idea where in the resolution cannot be specified without the presence of the contrast level does not make any sense at all. Both of them should be utilized and incorporated into the specification of the modulation transfer function.

What are the advantages of the modulation transfer function?

If you can determine the quality of an image regarding modulation transfer function, it can present several advantages if you’d compared it using other known methods. For instance, we all know that the modulation transfer function is some objective measurement. If you’d compare it to the traditional methods, the complete opposite of it, you can say that it will rely more on the visual testing. The operator will now judge the quality of the lens based on their observation from different targets. Because humans will eventually have some difficulty when it comes to gauging the contrast visually, the visual tests that are used are the means of identifying the highest frequency the operator will be able to see.

Therefore, all the results will just depend on the operator himself as well as the fatigue level of the operator. This method will not also be able to indicate contrast levels even at lower frequencies that is considered the main problem when it comes to the application because the contrast in lower frequencies is much more important compared to the limiting resolution. This is relatively true in any imaging applications that will sample a signal.

It is also helpful when it comes to the integration of the system because there are several components that are in the imaging system that is all linked with the modulation transfer function. This is relatively true, especially for the lens and camera. In short, the modulation transfer function is the fruition of the component MTFs only.

Aside from installing a burglar alarm system, there are a range of ways to make your home a safer place. You can look at each possible entry point of your home such as doors and windows to see how they can be improved. If you would like to get a burglar alarm installed using a company like is the best way to go.

As well as opportunistic burglaries, some burglars scope out a property beforehand, sometimes working with others. It’s therefore very important to think about what will ensure your home looks occupied at all times, that there aren’t obvious places a burglar can hide to assess the house and that their entrance to the house is visible and difficult. There are a lot of questions you should ask yourself and we’ve provided a list here:

  • Is it obvious when you’re on holiday or away from the home? For example, are you curtains always shut or is there lots of visible post?
  • Are windows and doors left open, even if they are not easily accessible?
  • Do your windows and doors have visible locks?
  • How well-lit is the outside of your home?
  • Is there a spare key that is easily visible, or easy to find, such as underneath the plant pot or above the ledge on the door?
  • Are the lights on or off all the time, making it look like you’re away?
  • Do you have high walls and hedges, which could give burglars protection from being seen?
  • Is accessing your house noisy for a burglar? For example, is there gravel outside they’d be crunching on?
  • Are there any ladders lying around that a burglar can use?
  • What equipment do you keep in your shed and garage? What is its value and can it be used to help someone break in?
  • How secure is the shed or garage? Is it always kept locked with high-quality padlocks and security locks?

These questions are something you need to ask yourself! Don’t leave windows unlocked or open anywhere in the house, no matter how small they are. Easily accessible windows should be double glazed at a minimum. Laminated glass or plastic glazing film is harder to break so consider this for easily accessible windows. If you have windows with key operated locks on show, this may put off burglars but remember to hide the keys out of sight and somewhere the burglar can’t reach if the glass is broken. Ideally, you should get locks that secure the window to the frame, rather than the ones that just secure the handle. Remember that whether you are in or not, a burglar can see into your home more easily if the lights are on and it’s dark outside, so consider net curtains or hiding valuables from sight.

In the end it’s about how you value your home and property and investing in a good alarm system is the best way forward to ensuring the protection of these things.
