They produced the smaller imaging core with lower resolution and no FFC shutter to serve a market that needs a tiny imaging core as a priority and is willing to accept the compromised performance that results. It cannot be made much smaller without some serious challenges along the way. Seek Thermal did a decent job of the compact QVGA thermal imaging core hardware design. All will add thickness and bulk to the core assembly. If you remove the FFC shutter assembly you end up with a PCB that is very low profile but unusable ! The SeeK thermal camera cores need the FFC shutter assembly to work and a lens is still needed to focus the scene onto the microbolometer. The lens assembly is part of the chassis module. If you dismantle the Seek Mosaic core you will have a microbolometer PCB with a solenoid module that drives the FFC shutter.
It is mounted remotely to address some local heating issues. The second PCB is on the end of a flex cable and is the same dimensions as the front (microbolometer) PCB. The PCB dimensions are those of the width and height of the mosaic module. The ‘front’ PCB contains the microbolometer and a few ancillary components such as an LDO, and sometimes a small ARM processor chip. The Seek Thermal Mosaic Core is a 2 part design. Resolution is not King if performance is severely lacking in other areas such as image noise and lens quality. Fraserįlyingfishfinger, To answer your question…… 1. You can be certain that Infiray (IRAY) and Guide Sensmart are not sitting on their hands and will be actively developing the next generation of miniature imaging cores. The frame rate restriction may be less of an issue but customers may start to expect 25fps as a minimum now that such is easily available. Some are still using Seek Thermal or FLIR cores but I cannot see that continuing for very long unless the US based cores become significantly cheaper, better performing and more easily obtained. They now have that choice with Infiray and Guide Sensmart These two core suppliers seem to dominate the budget consumer grade Chinese cameras now. Using Chinese imaging cores for Chinese built thermal cameras makes sense on many levels. Some time ago I recommended exactly this move to a Chinese thermal camera manufacturer. There appears to be a very understandable move away from frame rate limited USA sourced cores towards the high frame rate China produced cores. I keep seeing new models mentioned here, on the forum, and I always wonder which imaging core the OEM has chosen to use. Vipitis, I decided to focus on the miniature cores of Seek Mosaic size and smaller as these are what are appearing in the many budget thermal imaging cameras coming out of China at the moment.
