Electro-optics can be used in many applications from non-contact mapping of blood oxygen levels to having a laser receive modulate Wi-Fi signals. You will also find out about a MEMS device for building a “personal” electronic accelerator as well as a temperature sensor that’s immune to interference.
By using an array of red and near-infrared LEDs, a research team developed an optically based, non-invasive system for 2D mapping of the blood oxygen saturation across a patient’s skin.
Researchers mixed two optical outputs of a laser comb and modulated the result, then emitted this energy via an integrated dipole antenna to create an RF signal in the 5-GHz band.
A collaborative team is attempting to combine electro-optical physics and a silicon MEMS structure to create a chip-size electron accelerator, in contrast to the mile-long versions in use today.
By sensing optical-parameter shifts in a microresonator stimulated by a laser, a research team devised and tested a way to measure small changes in temperature with an EMI-resistant arrangement.
