Hello there:ko:  
I am a 3rd year student doing (electrical and electronics)…  
my final year project is  
**A webcam-based spectrometer (pc interface algorithm) using c++ or matlab**

A typical spectrometer in visible, infrared or terahertz range is usually bulk and expensive. Recently with the advances in CCD technology, miniature spectrometers are available with a price tag below ten thausands pounds. On the other hand, with the mass production, a typical webcam (and mobile webcamera) costs only ten pounds. this project is to investigate the feasibility of using a webcam as a spectrometer. The student will connect a webcam to a PC and develop algorithms to control/interface with the webcam.

**Anyone have any idea to help me plz?**  
**The advisor asked me to find somthing called (library),where can i download that??**

**thnx**
