  • Thermovision

    I didn't knew where to start this topic so i i put it here.
    Thermovision... can it be used in our hobby?
    I already mentioned new Flir production line recently, but couldn't find that topic.
    Search option didn't help me.
    Anyway...
    The other day i had chance to meet and test one thermovision camera made in China.
    Model was EasIr-4.
    Spent 1 hour playing with it.
    One huge remark i can put; is on it's tft display.
    I couldn't see clear picture at all on daylight. Not because of camera itself but mostly because that tft display is having very bad contrast and it is almost impossible to follow it on daylight.
    Only in dark room picture is getting viewable.
    Seller explained me that main problem is exactly in that TFT display and if camera is hooked on regular TFT, via proper cable, than such problem does not exist any more.
    Other impressions; nice! Fast firmware, real time displaying. Sensitivity is pretty good.
    I walked through a space and observed various things.
    First i made small paper "ocular" to protect tft from direct light, to be able to see least something.
    Seems seller was right, because sensor and machine inside really work nice.
    I was able to see power installations through walls.
    Tried to observe outdoor facillities through window, yet without much of success, because sunlight was potent at that period of a day.
    Camera have memory card and with a single press on button everything can be saved.
    Another button allows you to see real "non thermo" picture in real time.
    Don't know.. really don't know about this.
    Haven't chance at the time to test it on something which will help me to distinguish whether thermovision camera will be able to "see" underground facilities like tombs, tunnels and similar.
    So my questions and doubts remains unanswered yet...
    BTW price was 3300e!
    Hot!
    Next thing i intend to check is Flir HS324 Pro, most probably in next few months.

    Most of Roman tombs (for example) are not that deep, barely 1-2m underground.
    Those i have seen so far are made from ceramic bricks, large ones.
    Inside there is usual space approx. 2x2x1 (to1.5)m.
    So, pretty large "anomaly".
    Hopefully such anomaly will significantly disturb temperature on soil surface, enough to be "detected" and monitored using thermovision camera.
    That's theory, but i miss practice for now...

        Cool stuff!
        Not expensive as previous one!

              In this website there are a lot of interesting things. If you look carefully the equipment, I think some of them may serve to our hobby. The site is Spanish.

                Thanks!
                Those cameras differs in features.
                I will have to investigate a bit closer their important features to distinguish among them.
                Most probably those cheaper are not "long" distance and are low resolution.
                I am kind a new in those matters so will have to do research to understand better that.
                But prices up to 1500e are quite alright in case such camera can help us in our hobby.

                  There is a camera even cheaper, by 1174€. Kellyco also seen in there for sale these type of cameras.

                    An X-ray scanner could also be used for the localization of metals? Here is a portable.

                      Things like this will not work well, real thermovision in something cryogenically cooled, (liquid nitrogen or something), capable for 1\1000 deg. C resolution picture or so, not for xxxx E and not portable, even then very of limited use in this situation, FLIR imaging capability is limited by temperature difference resolution and many other things. X-ray imaging works only thru object, not for surface scan. We still need metal detectors.

                        Hi,

                        over 1000 Eur is hot, but good...

                        Making IR from the normal digital camera with an filter:


                        http://fototipp.hu/irdslr (with practical how-to description, please translate with google)

                        and

                        http://www.lifepixel.com/ (detto, English).

                        The poor-man IR filter is an part of the old floppy disk or black exponated celluloid film (replacing with the built-in CCD filter). Remember: the modified digital camera is IR only -- NOT normal photo.

                        With good IR-filter is making an very good IR-camera.

                          Hi,


                          i m known the thermovision and infrared is working with different technologies, but the

                          found historical reliquies is not always necessary the thermo.

                          An what do you think from Terahertz picture system?


                          Good hunting
