Selective Incident Headlight Intensity Measurement

[QUOTE="Henryk, post: 5760901, member: 568354"] there are so many ways to do it. Yes, one way is to use a pinhole or just a hole to limit the incoming light from one direction only. The drawback is that you will get very little light on your detector this way. Another way is use a lens and place the detector at the focal point. You will be collecting all the light hitting the lens aperture (read something about photography, aperture setting, etc.) Another way is to use a camera and some software to process the image and pick the maximum intensity of the light. One note of caution. The sensitivity of a typical detector or a camera depends on the wavelength of light in a manner that is different from the human eye response and you would need to use a filter to bring the detector response close to the photopic curve.
