Deflectors & Variable Frequency Shifters

주파수를 변경하면 출력 레이저 빔 각도가 수정됩니다. 디플렉터는 다양한 각도에서 레이저 빔을 스캔하거나 레이저 빔의 출력 각도를 정확하게 제어하는 ​​데 사용됩니다

A Bragg configuration gives a single first order output beam, which intensity is directly linked to the power of RF control signal, and which angle is directly linked to the RF frequency.

By varying the frequency, the output laser beam angle is modified. A deflector is used to scan a laser beam over a range of angles, or to control with accuracy the output angle of the laser beam. By varying the frequency, the first order beam is also frequency shifted by the amount of the RF carrier frequency: it acts like a variable frequency shifter.

The main parameters to qualify a deflector are 1. Deflection angle range and 2. Resolution.

The deflection angle range is the maximum angle variation of the laser beam: it is linked to the frequency range of the device. The resolution of a deflector is the number of distinct directions which can be ad- dressed by the deflector: it is linked to the deflection angle range and laser divergence.
Two deflectors can be used in serie and at right angles to give full two-dimensional scanning.
