on its front or back surface. A simple detector at the transmitter output (which can be little more than a loosely coupled diode) recovers the audio signal, and this is used as negative feedback to the audio modulator stage. Usually, an SLM modulates the intensity of the light beam. They can also be used as part of a holographic display technology. Displays using ferroelectric liquid crystals fLCoS ) or nematic liquid crystals (Electrically Controlled Birefringence effect). Low level, here a small audio stage is used to modulate low power; the output is then amplified using a linear RF amplifier. Generating Colour and, generating Greyscale. Each sideband is equal in bandwidth to that of the modulating signal and is a mirror image of the other. 9-19 (2001) Liquid Crystal Optically Addressed Spatial Light Modulator, 2 Slinger,.; Cameron,.; Stanley,.; "Computer-Generated Holography as a Generic Display Technology", ieee Computer, Volume 38, Issue 8, Aug.

2 See also edit References edit Larry. The reflected light, is circularly polarized in the opposite direction and, having passed through the quarter-wave plate a second time, is once again linearly polarized, but this time rotated by 90,.e. As its name implies, the image on an electrically addressed spatial light modulator is created and changed electronically, as in most electronic displays. Advantages, one advantage of using class C amplifiers in a broadcast AM transmitter is that only the final stage needs to kaylie jones essay be modulated, and that all the earlier stages can be driven at a constant level. It reflects back to the PBS and then to the light source. A suppressed-carrier amplitude modulation scheme is three times more power-efficient than traditional DSB-AM. Since then more modern projectors have been developed where the SLM is built inside the projector. SLMs are used extensively in holographic data storage setups to encode information into a laser beam in exactly the same way as a transparency does for an overhead projector. Disadvantages, a large audio amplifier will be needed for the modulation stage, at least equal to the power of the transmitter output itself. Beginning with Reginald Fessenden's audio demonstrations in 1906, it was also the original method used for audio radio transmissions, and remains in use today by many forms of communication"AM" is often used to refer to the medium-wave broadcast band (see AM radio).
