LASER DISTANCE METERS

Wether in geodesics, in security systems, production controls or just on the golf corse - the measuring of distances with lasers or laser-scanners is well established nowadays. The time - namely the time, the light needs to pass the needed distance - is the value to be determined. This sounds so simple, but it isn't - because the velocity of light is very, very high - it's 2.99792*108 m/s. In consequence one has to deal with very small times. In only one microsecond the passes 300 meters. A high resolution in place therefore demands highest resolution in time.

TDC ADVANTAGES:

• Direct conversion of time to digital values
• Highest resolution: down to 10ps (70ps peak-to-peak)
• Multichannel - TDC-GP1 and TDC-GP2 have two stop channels, TDC-GPX up to 8 channels
• Multihit-capability - TDC-GP1 and TDC-GP2 can handle 4 Stops, TDC-GPX up to 32 Hits
• High Update rates: TDC-GPX can measure with 200MHz peak rate
• Direct pulse width measurement: TDC-GPX can directly measure the pulse width down to 1.5ns
• Space savings: Single Chip-solution in a small QFN32, TQFP44 or TQFP100 package
• Industrial operating range: from -40°C to +120°C.
• Battery applications: for handheld devices a low current consumption is essential. Discover the TDC-GP2 - it's perfect for this! When you work in measuring range 2 with only one measurement plus calibration per second, the current consumption will be only 3uA for a 5V supply (Note: nearly the complete consumption is delivered to the calibration clock)
