The process of varying the AMPLITUDE of a sound, often periodically. An example of AM is the violinist's TREMOLO, where the amplitude of the vibrating string is rapidly altered by a movement of the ...

As a next-generation optical archive storage device for 8K video, we have been researching and developing holographic memory. Recent studies have focused on multi-level code instead of binary code to ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

Jenoptik is one of the few companies in the world to address the market for pulse modulation of high and low power lasers. The Digital Imaging business unit presents at Photonics West their highly ...

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission. New research ...

LASER COMPONENTS would like to introduce its phase modulator especially designed to operate in the 1000nm wavelength band. The NIR-MPX series use a proton exchanged based waveguide process that ...
