    How to calculate birefringence in lithium niobate LiNbO3

    I am thankful for anyone's time, let me try again. Goal: a rectangular wafer of that when placed in front of a camera image sensor will displace light(visible) 9 microns vertically, and how to specify it to order it properly! 1) LiNBO3 crystals available for purchase off the shelf are specified...

    How to calculate birefringence in lithium niobate LiNbO3

    I am trying to calculate what thickness of LiNbO3 would displace a beam of light 9 microns. I seek to make something like a microscope slide that would displace light in the vertical. I am confused about something else if someone can clarify; for the crystal, I think the "z" axis is "optical...

    What happens to projected light after the source stops

    The energy of the light is transferred to the atoms it comes in contact with, if it does... they then might pass on that energy in different ways. light, heat, etc.

    2 layers of birefringent crystal, how many rays?

    Thank you for taking the time to answer. I do not follow what you say here: "You can see what the whole setup does for one polarization axis of incoming light and for the other separately." could you expand please? In the question I posit 2 stacked crystals with the same orientation. You have...

    2 layers of birefringent crystal, how many rays?

    I understand that a ray of light entering a birefringent crystal becomes polarized into 2 perpendicular linearly polarized light rays that emerge parallel and displaced by a distance. If the 2 rays then pass through a second crystal with the same orientation, say for example the first crystals...

    2 layers of birefringent crystal, how many rays?

    I am trying to solve a problem my camera exhibits. It has a sensor with 6000x3376 pixels. HD video is 1920x1080. In order to reduce the amount of information to the processor the camera throws away 2 out of 3 pixel lines. this creates a problem with thin lines tike telephone lines and makes...

    ah rats, you're right.

    On the nature of vacuum and questions thereof

    hmm. I have tried this quickly and i was only able to pull the syringe a pretty short distance. (need to work out i guess!) but it made me wonder whether i was missing something. However, If the amount of force becomes a constant after the weight of atmosphere is equaled, this might make a good...

    On the nature of vacuum and questions thereof

    i have been pondering something. this is it: if a fellow had a tube with a plunger in it, like a syringe but without an opening for a needle or such. say the plunger is at the bottom of the tube. If you start to pull/raise it, it is my understanding that the force required to lift it would be...

    Would a syringe in space suck?

    Depends on how desperate you are? ;) This is a question of the nature of vacuums. Part 1- In the relatively pure vacuum of space, (for this case let's consider it pure please). Can volume of a closed chamber be increased or decreased without force? (other than the friction of materials, but...
