The laser line scanner consists of a balanced, rotating mirror and motor with position encoder, and mounting hardware for use with the AR4000. The scanner deflects the AR4000 sensor's laser beam 90 degrees, sweeping it through a full circle as it rotates. The standard encoder (Agilent brand) resolution is 4096 counts per revolution.
The Acuity laser line scanner has an elliptical mirror situated at a 45° angle to deflect the outgoing laser spot and the return signal. The mirror is engineered the highest optical standards with 96% reflectance.
Using the High Speed Interface Card, the line scanner can sample up to 200 KHz*. With a maximum mirror rotational speed of 2600 rpm, the line scanner can sample 4615 distance measurements per revolution.
Typically, engineers will use the AR4000-LIR rangefinder in conjunction with the line scanner because the LIR can measure to most surfaces in most conditions. Although the AR4000-LIR is a Class IIIB laser product, the laser class CAN BE reduced when operated with the line scanner. The line scanner sweeps the laser spot at very high speeds and the effective power is reduced. So long as the mirror is always spinning, the radiation danger to the human eye is reduced to the levels of a Class I laser (eye-safe). In these cases, the integrator is responsible for safety interlocks to guarantee that the laser is disabled until the mirror spins. For more information, go to Acuity's laser safety page.
