The MOOG CT Scanner Machine Parts Box Transmitter Laser Components is used in Moog High Speed Data Link as following pictures . You can see the red arrow. That's this laser diode components. One Moog CT Scanner machine has lots of laser diodes in it. Moog has High Speed Data Link. Moog has developed its patented Optical DataLink to transmit the high rate image data from the Detector Array (DAS) across the rotational interface of the CT gantry.

With CPL and GND filter in place (if required) use the cameras light meter and the histogram to get a perfectly exposed shot.  Once you have this base shutter speed it’s time to get the NiSi App and input this and select the ND filter to get to the target shutter speed.

Here’s how the theory works…For each stop of light blocked by the filter, the shutter speed doubles in duration.Let’s check out an example: If your shutter speed is 1 second (base or normal exposure) for a scene without an ND filter, then using a 3 stop ND filter will require an 8-second shutter speed to achieve the same exposure: 1 second (original shutter speed) x2^3 = 8. You may have noticed that the value needed to multiply your original exposure follows one of the naming systems of ND filters. In the above example, a 3 stop ND filter is also called an ND8.Let’s go through another example using a 6 stop filter. If your shutter speed without the filter is 1 second, you will require a 64-second shutter speed to achieve the same exposure: 1 second X2^6 =64. Note that a 6 stop ND filter is called an ND64 filter.Most DSLR cameras can calculate exposure times up to 30 seconds and some mirrorless cameras up to 60 mins with an ND.  If the target exposure time is over the limit your camera will calculate, you can use an app to help.Most of us are not math geniuses so there’s an app to calculate your exposure times when using ND filters.
