3D active glasses
Wireless battery-powered glasses with LCD shutters. Synchronization information is communicated to the glasses by means of an infrared
(IR) or radio frequency (RF) emitter which is connected to the Sync Out terminal on the projector. IR or RF pulses are transmitted by the
emitter to signal when the left eye and right eye images are being displayed. The glasses incorporate a sensor which detects the emitter’s
signal and synchronises the left and right eye shutters with the projected image.
3D passive glasses
Passive glasses do not require a power source to work. Light with left-hand polarisation can pass through the left lens and light with right-
hand polarisation can pass through the right-hand lens. These glasses are used in conjunction with another device which polarizes the image,
