The pulse laser rangefinder calculates the interval by measuring the time between laser emission and return. Therefore, time measurement is very important for pulse laser rangefinder. Due to the special speed of the laser and the time interval between the laser pulses is very fast. For example, to measure the interval of 1km, the resolution of 1cm is required, and the resolution of time interval measurement is as high as 67ps.
Eight advantages of laser tube for Laser Ranging:
1. Convert time to digital output directly without DA conversion
2. The resolution can be as high as 65ps, and the accuracy of single measurement is 0.98cm
3. Two stop channels can be measured at the same time
4. Each measurement channel can measure 4 pulses
Continuous data output rate of 5.1mhz
6. Qfn32 package, small size, especially for handheld laser rangefinder
7. Working temperature scale: - 40 ° C - + 125 ° C
8. Ultra low power consumption. If you choose measurement scale 2, measure and calibrate every second. When the power supply is 5V, the current consumption is only 3ua!!! This low power consumption makes TDC-GP2 especially suitable for hand-held range finder!
