@Carl: Short answer: yes it can.
Long answer: Lets just say it is a non trivial project. Here are the two main approaches we have seen:
Looks like a really useful device. It looks like a really good piece of kit. However I am currently living in Japan. I guess standards with regards to laser power are different here, so it may not be possible to use it or purchase it over here.
i am looking for lidar lite V2 but i cannot find anyplace to puchese it. do you know where can i get it? or maybe a good replacment for it?
thanks
@Eran: Earlier in January 2016 the manufacturer of the LIDAR-Lite was purchased by another company. Since then. they started moving production to a new facility (and a different country), so there is none being produced right now. For now, a potential replacement may be RB-Plx-317.
@Paul Creaser: You may not have any issue, actually, since Japan is a full member of the IEC (International Electrotechnical Commission), as seen here. Products on our website usually specify their ratings using the “IEC 60825-1 - Safety of laser products”. From what we understand, the equivalent in Japan is the “JIS C 6802 - Safety of laser products”, and while it is translated into Japanese in order to comply with the JIS standard, the technical contents have not been changed.
hi
do you know what the idea from using a mirror and spinning the sensor it to provide a 360 scan instead of just spinning the sensor ???
@sam: It is much easier to simply spin a mirror around then the sensor itself. By doing this, you do not need a slip-ring since the mirror has no wires.
ok thanks
i have question about the difference between 2d and 3d laser scanner ???
@sam: A simple scanner, like the LIDAR-Lite, only returns a distance (1 dimension). A 2D scanner would normally return polar coordinates: distance & angle. Following the same logic, a 3D scanner would return spherical coordinates: radial distance, polar angle and azimuth angle.
ok thanks
i have 2 qustions
1-where i can find information about using mirror to scanner (type of mirror, how it should be ,which angle ) and every thing else ???
2- how measurements not affected by angle of incidence laser pulse assuming 2 causes (mirror,wall) and in both causes angle of incidence is not 90 dgree
@sam: We recommend that you perform a quick online search, such as searching for “lidar-lite rotating mirror”. This should find plenty of examples implementation.
sir, i can’t find the source code.great thanks
Hi, thanks so much for the code. Just got one question to ask, My project is using two servo motors which do the vertical part(height) and the horizontal sweeping part. So do I need to change something in the part of ‘Get a measurement from the LIDAR Lite’ . Caz I have tried just adding a new variable (height) and the servo motor sweep just vertically slowly. Thanks for telling me I am new on this sensor.
@chinalu: You can find the source code link for this example under “Source Code” here. Here is a direct link. For the libraries from the manufacturer, you can find here.
@Otto: To add a second servo for vertical control, you would need to make a few changes, such as adding a second servo object/variable here, making sure it is also attached here and then controlling it in the main loop. To do a basic 2D scan, you could simply add a second loop to control the new servo around the other ones already there for controlling the horizontal positioning. We recommend that you post about your project on our Project Showcase section of our forum.
Hello, I was wondering if you can point me in the right direction, I want to find a laser that i can take a reading from, almost like a depth gauge, at a distance of about 10cm away. The marking depth would be in less than a millimeter deep…? Thanks for your reply.
@Rico: You can find our laser range finder products here. The best ones we currently offer have an accuracy of 0.1 mm under 10 m, but the resolution of the measurement is 1 mm, so it would most likely not be helpful for your case.
And I want to build a military radar detector, those that detect the distance cars to apply fine. Can you tell me which component to use the Arduino to identify the presence of a radar of these at least 500 meters before? I understand the pistolinha radar is a laser.
@omar You mean police radar detector which detects speeding cars? Its easier to simply purchase a unit.
