Is there a sensor that detects the laser light or LED?
I am looking for a sensor that can detect the LED or laser light. I'm guessing that would be a sensor infrared, but Im not sure what type it is because I want the sensor to measure the distance of the LED or laser light is the sensor. I would also like that is able to distinguish between more than one wavelength and calculate the distance of each. Is there a sensor there that can do that?
Yes and no. Detectors light it. And, of course, have existed for millions of years. There are many examples in biology, but we will mention only one eye. Or what about the movie Picture? I suppose it's what you want. You probably want some type of electronic device. Many types of these also exist. Things like photo-resistors sensitive, as mentioned by another answer. There are CCD devices used in digital cameras. There photomultipliers. But most of the 'laser to detect' is done with a photodiode, which is a small low cost device that can vary from 1000's of dollars and 10 cents, depending on their characteristics. However, to use one, you either need to buy a pre-configured e-book, or if you need electronics knowledge to create your own. Thus, light detection is the easy part. But you want something that can tell distance. Of course there are things to do this, too. But here's the problem. This is a complex problem that requires a sophisticated solution. How the works of sensors will depend on exactly what the signal it is receiving. You could not simply shine any old laser on it and wait to see how far that is laser. You could reach their own solution that fits your specific laser, it could take months if not years of effort. But then there is no job for a different laser or a different configuration. So there is no device that can be used to count the distance from a light source arbitrarily. Most devices come with a specific light source is intended to be used with (as the detectors in the DVD or laser rangefinder) and that the light source to be used in a specific way. This is somewhat similar to a device that makes food. There are plenty of devices that make the meal, but not necessarily a device that will make you want food now. In distinguishing wavelengths, there are also many ways to do this. Most light detectors only work for a range of wavelengths. So if you try out light of that wavelength will not be detected. Moreover, all the light within that range can not be distinguished from other wavelengths in that band. The way we distinguish wavelengths obtained two detectors, one who works at one wavelength and another who works in the other wavelength. Then you can say that the wavelength range of light is in That's like cameras, film, eyes, and almost any color sensitive detectors work. To conclude, there is a pre-assembled device who does what he wants for a light source arbitrarily. I am sure that something exists for certain light sources, although I am sure that these devices could be expensive. And all existing components, so if you are ingenious enough to make your own device for these components, it is certainly possible (though will require a great effort). And let me conclude by saying that I have overlooked an obvious device that not everything you want: the human eye. You can tell the distance and color very well. Of course, if you think about how complicated the human eye, together with the intricacy of the transformation is taking place in the brain to do all these tasks, then have an idea of how complicated the problem is that you are asking. And remember, the human eye has had millions of years of evolution to get where he is now.
