| Abstract: | Based on the Kubelka-Munk theory, a practical diffuse reflective measuring instrument using diode laser InGaAs/Ias light source, using LiTaO3 pyroelectric detector as light receiving unit and using 8031 chip-processor as processing center is presented. This instrument is composed of light emitting and receiving system, signal amplifying and controlling system and display system. The structure and the principle of the instrument are described. The key technologies and the corresponding solution methods are briefly discussed. Some experimental results are given. |
| Keywords: | applied optics measuring instrument Kubelka-Munk theory measuring water content laser diode |
