polarizer

1. An optical element or a device that produces polarized light from incident unpolarized light. Examples: Nicol prism, Polaroid sheet, tourmaline crystal. To see that light is polarized, another device called an analyzer is necessary. 2. In a polariscope, the first of the two polarizing elements, the second being the analyzer. See polarized light; polariscope; Nicol prism.

Patient discussion about polarizer

Q. Can bi-polar be treated with acupuncture and Chinese medicine? Any help would be appreciated. I am a bipolar. I always get side effects from the meds being prescribed by my psychiatrist. I feel better one day but the very next day I feel moody and have outbursts even on meds as if I am not after them. I wish to follow a different system of treatment. Can bi-polar be treated with acupuncture and Chinese medicine? Any help would be appreciated.

A. Do a lot of research before coming off your meds. You should consult your doctor about how to come off your meds safely. First arm yourself with information about what the effective treatments are and how to get those treatments.

Q. My brother-in-law named Jacob has bi-polar schizophrenia; please help us by giving some solution for this… My brother-in-law named Jacob has bi-polar schizophrenia; he is currently on his medication and takes them faithfully in a positive mood. We have a hard time communicating with each other and it's destroying our marriage, please help us by giving some solution for this…

Q. Is spending money irresponsibely a sign of impending manic attack? My 32 years-old husband is known to have bi-polar disorder, but for the last ten years he has been on lithium treatment and had no attacks. Last week he bought some very expensive things to our home, without asking me (we usually discuss these things before we do anything). Does this mean he’s getting a new manic attack? Other than that purchase everything else is normal, and he appears and behaves as usual. I don’t want to take him for the psychiatrist just for spending some money.

A. Spending money is not a unique character of bi-polar people... Maybe it was a bit less calculated action. If he has manic attack, usually there'll be more things that would tell you about it.

LG Chem is the world's largest manufacturer of large-sized polarizers and occupies 30 percent of the Chinese market.
where T is transmittance of optical components, CF is the color filter, BUMP is the region with a bump, LC_BUMP is the region of the liquid crystal (LC) with a bump, PF is the polarizer or analyzer, TFT is thin-film transistors, and [I.sub.in]([lambda]) is light source spectrum.
When beams spread to the filter using FSS or polarizer with distance D3 = 172.1 mm and D4 = 162.86 mm, the beam propagation direction of T-183G and T-324G is reflected and transmitted dividedly, where the reflection angle has [theta] = 30[degrees] and then the double beams are synthesized into an emergent field by sharing the same reflection mirror M3 with a distance D5 = 92.12mm.
Furthermore, the CP polarizer has been simulated at oblique incidences.
