Optical mount

Optical mount is a mechanical part of optical systems, determining the alignment, robust, and precision. Any variation would affect optical performance in geometric and these factors are vibration, temperature drift, acoustic fluctuation, shock, chemical corrosion...etc.

Mirror is particularly sensitive to any fluctuation because any geometric variation would amplify the change of optical path. For example, angle tilt of mirror causes reflection angle double.

Pixel Qi and CPT

Pixel Qi corporates with Chunghwa Picture Tubes (CPT) in mass production of trans-reflective  LCD. Pixel Qi LCD, a E-ink killer, is really very impressing. But the market is not big. So the good news can't help CPT away from deficits.

蠻有趣的消息, Pixel Qi這樣電子書E-ink殺手的產品是還蠻有吸引力的

可是這方面的市場還不大, 無助於岌岌可危的CPT

Nano Loa: PSS LCD

Nano Loa, Inc, started at US but people from Japan, devotes to develop fast and wide-view-angle liquid crystal display –Polarization Shield Smectic (PSS).

PSS is a very interesting technique in liquid crystal display. Nano Loa claims PSS faster more than 100 times than conventional LCD.
