I wish to synchronize a thermal camera FLIR A300/600 with a test section on a rotating shaft such that whenever the section becomes orthogonal to the line of sight of the camera, an image is clicked by it automatically. The camera uses a TTL pulse input. Being a mechanical engineer, I have little idea as to the electrical components involved. However, I have thought of placing a proximity sensor on the mutually orthogonal axis in front of the section, such that whenever it detects an obstacle(the test section), a pulse is sent to the camera. I wish to confirm whether this will work before actually implementing it on the expensive camera. Also, if someone has used a similar setup can guide me as to what all settings are needed in camera software and whether the pulse output by proximity sensor(PNP) is in compliance with the camera.
