Why is the StereoMirror technology better than shutter glass stereo monitors?
Stereoscopic CRT (cathode ray tube) monitors display left and right images sequentially at a refresh rate of 100-120 Hz. The user can wear special goggles that have a liquid crystal shutter alternately blinking in front of each eye at 50-60 Hz, so the left eye can see the monitor when the right eye can’t and visa-versa. These active glasses are connected to the computer to synchronize the electronic shutters to the sequential frames on the CRT either with a tethered cable or infra-red beam.Another approach is uses a large pi-cell LCD that overlays the CRT screen. The emitted light is flip-flopped between clockwise and counter-clockwise circular polarized light. The operator wears passive polarized glasses. In either case, this shuttering can cause the image to flicker. The advantage of the SD monitors is that both eyes view image content continuously, which allows for much more comfortable viewing and significantly higher brightness.
