Reading at 30Hz gives you the best image quality, sampling the exact same frame rate twice for the supposed improvement in motion detection degrades the image and give you two frames of the exact same thing minus the microseconds needed to complete the capture.
60Hz may be of some minor benefit if the majority of your night thermal hunting is out the window of a sport car at high speeds at night, otherwise forget about it....
Wow I did know this.
thanks
In addition, as far as LCD vs OLED diplays go, there are lots of differences positive and negative between LCD and OLED displays, however all the genuine FLIRs are LCD and not OLED.
The human eye can only discern about 400 maximum levels of gray and the 2 to the 8th power or 256 levels of gray is what both displays are capable of putting out, so really don't see that as a problem for either of them.
Even if a display is capable of putting out the next step up of 2 to the 16th power of 1024 gray gradients, it would make no difference to the human eye as it is limited to the ability to detect less than half that distinction.
It is kind of like the controversy over 30Hz vs 60Hz., the read out circuit can certainly put out 60Hz but the microbolometer thermoresistor circuit refresh rate is limited to 30Hz, so 60Hz is just reading the same frame twice which results in less image quality at the supposed improvement quality of more motion sensitivity, so it is kinda more a marketing tool than anything actually improving something....I'll stick with 30Hz myself.
People do not realize that the proprietary software that drive these cores is IMPORTANT!
It takes allot of time to create and polish AND IT IS NOT FOR SALE, whatever company purchases a raw core from whatever company producing cores for sale has to DEVELOP THEIR OWN SOFTWARE ALGORITHMS to produce an image beyond the included OEM software drivers that come with it for basic operation. This is a man hour intensive project.
Most often it pays dividends to purchase your thermal unit from the same genuine OEM manufacturer of the cores and the software drivers/algorithims if you have any long term use planned for the instrument besides being a novelty device.
