@eneuro,
Nice work on the images
My SEEK is still a Virgin, unmolested and case still tightly sealed
I can take some better pictures if needed from different angles. The second image was not great as the SEEK was just sat on its side at an angle to the detector array. There is a single rectangular shutter aperture in one side of the lens 'tube' and the X-Rays are punching through the other side wall producing the contrast where the aperture is located.
I took a look at the formats that the Faxitron software can save in and I am pleased to say that it offers "Lossless" JPEG, BMP, TIFF and RAW.
In the images you can see a possible reason why the Faxitron was taken out of service. One or two of the cameras panels are more grainy than the others. I will need to check that this is not something that can be "tuned out" via calibration settings. From my point of view it does not spoil the images so is no great concern.
Not on topic I know but some might still find the technology interesting
....
If anyone is interested in what the Faxitrons/Bioptic camera Teledyne detector array looks like, take a look here:
http://photonics.engr.uga.edu/xray_imager/index.htmlEight 512x1024 detector panels to create a 2048 x 2048 imaging array. I believe Eneuro had a thought about similar arrays with SEEK microbolometers. High resolution imaging at an affordable price ? Image stitching and optical distortion could be issues though.
Update.
OT.... having just looked at the Bioptic imaging array schematic I suspect my unit has a noisy op-amp or supply rail to such. Each 512x1024 diode array feeds a differential ANALOGUE output to an AD462 amplifier, that in turn feeds the signal to an AD9240. Something before the ADC is injecting noise onto the analogue signal path for that specific array panel. A job for another day though as way too much going on at the moment (plus the Faxitron weighs 70kg and I don't fancy lifting it to get to the base mounted camera!)
