LIGHT PATTERN RECOGNITION AND PROFILING USING MODIFIED CCD CAMERA

The main objective of this project is to design an instrument, which enables
the production of a profile of a pattern due to variation of light intensity. The light
pattern recognition is obtained from the light intensity distribution profile. The light
beam pattern recognition can be widely used in various applications such as profiling
reflection of light from irregular surfaces, bar code intensity analysis and particles
sizing for biological cells characterization. The light intensity distribution patterns
can be observed using light-sensing element and the methodology behind the design
requires designation of light pattern capturing device that gives analog signals at the
output, which canbe observed on an oscilloscope. These analog signals represent the
voltage variation proportional to the light intensity distribution. The design of
circuitry part is included in this report, which discusses the contribution of each
circuit element towards the working of the prototype. At the end of this report,
conclusion and recommendations are made to summarize up the overall project.
