A pulsed laser range finder calculates the interval by measuring the time between laser emission and return. Therefore, time measurement is a very important part of pulsed laser range finder. Since the speed of the laser is extremely fast, the time interval between the transmitted and received laser pulses is very small. For example, to measure the interval of 1 km, the resolution requires 1 cm, then the resolution of the time interval measurement is required to be as high as 67 ps. The TDC-GP2 of ACAM of Germany.

Laser tube 8 advantages of laser ranging:

1. Convert time directly to digital output, no need for DA conversion process

2. The resolution can be as high as 65ps, which is converted into an interval, that is, the single measurement accuracy is 0.98cm.

3. Two stop channels can measure simultaneously

4. Each measurement channel can measure 4 pulses

5.1MHZ continuous data output rate

6.QFN32 package, small size, especially for handheld laser range finder

7. Working temperature scale: -40 ° C - +125 ° C

8. Ultra low power consumption. If you choose the measurement scale 2, once a measurement and one calibration per second, when the power supply is 5V, the current consumption is only 3uA! ! ! This low power consumption makes the TDc-GP2 especially suitable for handheld rangefinders!
