The Microtrak™ series laser scanner from MTI Instruments incorporates high speed, line scan, and CMOS sensors that sample at up to 40,000 samples per second. While a dichroic filter cuts down on ambient light, a high-speed closed loop servo controls the intensity of the laser to optimize for average road conditions.
The cut time feature detects loss of signal where the laser spot falls into a crack and the line scan sensor can’t detect a return. In this event, the laser sensor processor automatically holds the last known value for a short period of time (user programmable) until the laser spot on the road surface again becomes visible. Typically, the LTS-300-200 laser sensor head is the best choice due to its 300 mm standoff and 200 mm measuring range. The laser heads are IP-67 sealed against the environment and can tolerate up to 16 G’s of vibration.
