With a National Instruments PCI-7833R DAQ Board, two analog output channels send an X-axis and Y-axis coordinate to an X-Y galvanometer that changes the mirror angle
for the laser-beam delivery.
Once the detector arm has been aligned to properly place the reflected beam on the camera, the mirror angle
is then changed by a known offset to place the beam onto the detector.
An electronic memory gives drivers their unique preferences of seat height, mirror angle
, temperature and favourite radio station at the touch of a button.
For each of them you can programme in the seat positions, the mirror angle
, the radio stations, which will be set as they enter the car.
Two Linear Varying Differential Transformers (LVDT) measure the mirror angle
