Photonics Dictionary

motor controllers and drivers: Motor controllers and drivers in photonics are electronic devices used to control and drive motors that are part of photonic systems. These motors are often used in precision positioning applications, such as adjusting the alignment of optical components, tuning laser systems, or moving optical stages in microscopy and spectroscopy.

Function: Motor controllers manage the operation of a motor by receiving commands (often from a computer or microcontroller) and translating them into signals that control motor parameters like speed, direction, and position.

Types:

Servo motor controllers: Provide precise control over the motor's position, speed, and torque, often using feedback from sensors like encoders.

Stepper motor controllers: Control stepper motors by sending pulses that rotate the motor in precise steps, allowing for accurate control of position.

DC motor controllers: Control the speed and direction of DC motors by varying the voltage or using Pulse Width Modulation (PWM).

Applications in photonics: Used in laser tuning systems, optical scanning devices, and precision positioning stages where exact control over motor movement is necessary for tasks like aligning optics, focusing lenses, or scanning samples.
