AccuRange 4000 laser range finder
By Stephen Schaum Fall 2005 ITP Data Sheet summary.
This is a datasheet report only. This sensor has not yet been tested by anyone in the sensor workshop class as of Jan. 2006.
I chose this sensor because it could be used as a spatial scanner. Check out this paper(http://robotics.jpl.nasa.gov/tasks/tmr/papers/LaserRangefinderPaper0900.pdf).
Other interesting sensors and sites are:
this means that the sensor sends 3=6 bytes of data to represent the calibrated output, and finishes each reading with a carriage return (ASCII 13) and a linefeed (ASCII 10). Since it uses LF and CR, you can probably assume that the output value is also ASCII-encoded too. In other words, you're not getting a raw value, but a string of characters, e.g. "123.45". What's the range of the output, and in what units? -tigoe
The range of outputs:
Pulse Width Output Uncalibrated range output on power/signal cable (standard with HSIF board) 18 - 50000 Hz, 0.5V peak to peak square wave signal
Low-level Outputs (standard): Voltage outputs are 0-5 volt analog levels.
Binary Calibrated output: 3 bytes:FF terminated?Low-level outputs: 8 bytes;FFF terminated
- Low-level outputs: 9-24 bytes: CR,LF terminated
FF terminated means it uses an ASCII Form Feed character (ASCII 12) -tigoe
- RS-232(standard) ->3000-38.4 K baudAnalog signals (optional);->4-20 mA current loop installed internally, configurable zero and set points.Pulse Width Output:-> Uncalibrated range output on power/signal cable,
- 18-50000 Hz, 0.5V peak to peak square wave signal
- enable/disable serial data output
- set baud rate
- set seial data output to ASCII or Binary
- Set analog Output between calibrated or uncalibrated
- Set min or max valid amplitude
- Serial output: 700 HZ
- Analog Output:1000 Hz
- High speed interface: 50,000 Hz
- 0.2 samples/sec. or sample on request
So the question is how to get a lower price spatial scanning system with a similar range...Hack some range finding binoculars? Sonic imaging?
