I'm trying to use a JAI AD 081 with a external trigger (I'm suplying with 19V in pin 6) but I'm not getting anything with every configuration at JAI CONTROL TOOLS. Camara does not capture when I activate photoelectric sensor (+19V).
Dear Roberto, I checked the trigger input for that camera and I think you are using the wrong pin for the trigger. You need to use 'Trigger 1 in' - Pin 10 and Pin 8 for GROUND. Please double check, whether the trigger input a) can handle 19V b) 19V will provide a logic high signal as some cameras require 24V for example. I don't have the user manual handy, just a brief technical sheet. I hope that helps. Best, Markus Tarin www.movimed.com
I am interested in buying a thermal camera 640x480 resolution for education/research in spectrum blending with standard daylight cameras and night vision. I want to write my own software in "Processing" a JAVA based programming language that would allow me to interact with the various video streams form these cameras.
Dear Matthew, We are a FLIR Distributor and can help you with a thermal camera. You can check out the FLIR A615 on our website. That camera has a GigE Interface and is GenICam compliant, which should make the integration pretty straight forward. We usually use National Instruments LabVIEW and their Vision Development module, which supports the GenICam protocol, however there are also others. The camera outputs a 16-bit image with calibrated temperature information.
I am looking for a Camera Link camera based on the new Sony ICX-674 CCD. Does anyone know of any? (I've evaluated cameras based on the Kodak KAI-02150 CCD, but am not happy with the image quality (tap balance).
Hi! Yes, the Prosilica GX 1920 from Allied Vision Technologies. We are a distributor. Send me an email and I can send you a quote.
What kind of tolerance can a camera inspect to? Lets say a 3 inch by 3 inch square, how accurate?
This is more of a system's question. The answer will depend on the camera resolution that is chosen. For your example field of view of 3" x 3" or 76.2mm x 76.2mm we can maybe assume the following: If you use a camera with 1,600 x 1,200 pixel. Then you can calculate the spatial resolution (theoretical resolution) this way: 76.2mm/1,600 pixel = 0.0476 mm/pixel or 0.00187"/pixel in for the horizontal image dimension. Just to give you an idea. You can of course select a camera with higher resolution to get more accurate. Camera sensors come in different aspect ratios. If you are always looking at square parts, then a 1:1 aspect ratio maybe better. There are also 4:3 and 16:9 aspect ratios, resulting in more or less rectangular images. However, in order to properly design a camera based measurement system, you will have to consider a whole lot more. For example the type of lens, illumination, filters, measurement algorithms etc. etc. Call or email. I can help with whatever you need.
Could someone explain more about ‘Sheet Lighting’? I believe that it uses a structured light, but does it employ a line scan or area imager? Can it be done with an area imager (sensor)? Can someone tell me how to do this?
Hi Bill! The type of lighting you will need for your imaging application depends on several factors, such as the surface structure of your parts and what you would like to inspect. The term sheet of light is commonly used for 3D imaging using laser triangulation. We have some explanations on our website as well: http://www.movimed.com/moviSCAN_3D_Cameras.htm However, the best way to go about your application is to get a few sample parts in our imaging lab and to figure out the best way to enhance the contrast of the features of interest you are trying to examine or measure. If you can email me some photos of the parts I can comment on a possible approach. We have solved a lot of medical/health care type imaging applications.
I wonder if there is any type of infrared camera that can measure the thermal temperature of the PCB through the white or black plastic cover.
Hi! We have a special thermal IR system that can potentially deal with this. We are using 'Lockin Thermography". This is performing a lockin measurement together with a stimulus to the object. In your case it would be some electrical signal. Feel free to contact me for further details.
Hello, I have an array of devices that I want to analyze optical properties by projecting onto a diffuser and have imaged with CCD camera, I want to measure 1. radiant flux of each device 2. the divergence of each device 3. the location of each device I have looked at labview with the vision module but i hope to find something more OTS (note vision builder does not appear to have capability to perform #1, which is most important)
Dear Andrew! We have been developing custom imaging solutions for 11 years using National Instrument LabVIEW tools, such as the Vision Development module as well as Vision Assistant and Vision Builder. If you generally like Vision Builder, we can assist with writing a custom vision algorithm as a 'Plug in' to overcome any limitations that you may face with that tool. That way you can still use a 'configurable' machine vision software with all of its inherent advantages, while solving a more complex imaging challenge. Alternatively, we can develop a custom application as a turnkey solution.
Is there vision software that specializes in inspecting porcine tissue for defects?
Hi Miguel! We are actually familiar with that exact application. We have worked with your heat valve division on this before. Please contact me to discuss further.

Dear Myles, We design and build custom imaging hardware. Please feel free to contact me to discuss in detail. Best,
I have a requirement to test a camera used in our medical imaging systems. The image originates from a 1K x 1K CCD sensor but the actual output of the camera where I need to test and measure is analog. I would like to reconvert the signal to digital and ideally into Camera Link compatible format with minimal affect on signal quality. I would like to use a frame grabber board but I have not seen any that will accept analog input. Can you recommend a solution?
Hi! We have built custom camera interfaces many times before helping companies convert from either an obsolete legacy camera to a newer version or to adapt to a different system. Since your application is a medical device you may be concerned with implications involving FDA validation. Let me know, if you can't find anything off-the-shelf. We can help with custom design. Best, Markus
Are you aware of a successful machine vision inspection application where the inspected part is imaged while it is on a vibratory linear track?
Hi Tom! We are up the street from you in Irvine. We have a lot of experience imaging parts under vibration. In fact we have developed a few systems that actually characterizes the vibration itself of parts which are ultrasonically excited. I'd be more than happy to discuss over the phone or in person at your convenience. Best, Markus
I am looking for talented vision system engineering resources to supplement our current staff. Can you help identify vision system engineering firms that will work on a contingent engineering (T&M) basis? My company is based in Corning, NY but we have facilities worldwide.
Dear Edward, My company provides custom imaging solutions on a T&M basis. We are located in Irvine, CA and have an East Coast Office near Boston, MA. We specialize in 2D, 3D as well as thermal imaging applications. In fact we have looked at an application for Owens/Corning in Ohio before. It was a thermal inspection for a fiber glass web application. Please see our web pages for more information. I look forward to discussing details with you in person.
I am looking for a vision system (cameras, stands, software and PC, etc.) that can be used both for teaching and research.
Dear Hamid! We can put together a vision system to meet your needs. We have a two tier approach, in that you can use the system for education using a configurable machine vision software and for more involved research applications you can program custom algorithms, if you so desire. We will have to work out the details of what your exact requirements are. Please contact me at your earliest convenience.
