Abstract: An optical measuring device includes a case, a reflective layer and a light collecting lens module. A measuring chamber and a channel, which is connected to the measuring chamber and is connected to an opening of the case, reside in the case. The reflective layer is disposed onto an inner surface of the measuring chamber. The light collecting lens module is located inside the channel. A light beam emits into the channel of the optical measuring device through an opening, passes through the light collecting lens module and enters the measuring chamber afterward.

Abstract: An image ranging system has a light source module having a light source diode and a light source lens, and an image sensing module, placed near the light source, having an image sensing device and an image sensing lens. An optical signal emitted from the light source diode passes through the light source lens with a luminous intensity profile which is characterized by intensity I1 and then reaches an object. A reflection signal is generated by the object. The relationship between the intensity I1 and the emission angle θ of the optical signal is I1=1/cos 7θ. The reflection signal into the image source lens has an incident angle θ the same as the emission angle of the optical signal, and images the object onto the image sensing device. The ratio of the height of object image to the effective focal length of image sensing lens is proportional to sin θ.
