Optical Meter
Can someone explain these optical tests?
I was just wondering what these tests below are. If you could explain them I would appreciate it. Are these something any local optometrist can perform?
- Ductions, versions, cover test and alternate cover test in primary and 6 cardinal positions of gaze.
- AO Vectograph Stereopsis Test at 6 meters (4 line version).
- AO Suppression Test at 6 meters.
- Randot or Titmus Stereopsis Test.
- Red Lens Test.
I have to go soon, but i will try to answer this as quickly but thoroughly as possible since no one has responded 
Ductions - Testing ONE eye, so the other eye will be occluded. You will perform an H pattern using a transilluminator at ~40cm and have the patient follow the pattern. This tests your eye muscle. This checks for the 6 cardinal positions of gaze.. up left, left mid, left bot.. etc. Each position mainly uses one of your six ocular muscle.
Versions - Testing BOTH eyes. This is a double H motion.. so l-l-l. Its the similar to as a duction test but does so binocularly. It tests to see how well your eyes (muscle) are working together.
AO Vectograph Stereopsis - Ive never used this test before, but we briefly went over it in class. It is a polarized chart, so the patient has to wear special glasses for this test. One eye will see a slightly different image than the other. This will in turn allow the patient to combine the slightly different images from both eyes and will result in a single 3d image. It tests for the depth perception at distance of the patient.
AO Suppression - Im guessing that this is a similar chart as the stereopsis one. This time, it is checking to see if one eye is suppressing. One eye will see a different marking than the other. If the patient sees both markings, then both eyes are working. If they only see the marking from the left eye, then the right eye is suppressing.
Randot - This is testing for depth perception at near.
Red Lens/Glass Test - You place a red lens in front of one of your patient's eyes. They will then look at a light source. One eye will see a spot of white light and the other eye will see a spot of red light. You will evaluate the patients eyes by where the light is located. For instance, the red light could be to the left, right, or directly over the white light. It tests the natural positions of your eyes.

Tachometer - Ditel Frequency Meter and Infra Optical Sensor
Buying a new camera need help with main features?
Hi, i just needed to know what a few of these specifactions meant for a digital camera:
feel free to answer as many as you like:
Color Support Color.
Optical Sensor Type Super HAD CCD .
Exposure Metering Multi-segment.
thanks so much, these are just some i didn't know what they meant.
10pts most answered?
Super HAD CCD
CCD is the sensor which captures your picture. (The equivilent of the film in a film camera)
Super HAD is an improved type of sensor, which in theory takes better pictures than a standard CCD.
here's an article about it.
http://www.mintron.com/HTM/Q&A/Htm/Super%20HAD%20CCD%20camera.htm
Color Support Color - I imagine that this means that it takes color pictures - (As opposed to black and white)
Exposure metering Multi-segment - this doesn't mean anything as all cameras do this. It just means that the camera can measure how much light is available, and properly expose the picture.
