  1. Photodiode Array

  2. What does it look like? http://lw.pennnet.com/Articles/Article_Display.cfm?Section=ARCHI&Subsection=Display&ARTICLE_ID=36131&KEYWORD=ingaas%20photodiode%20arrays&p=13 http://www1.shimadzu.com/products/lab/spectro/multi.html

  3. How does it work? http://elchem.kaist.ac.kr/vt/chem-ed/optics/detector/pda.htm Basically, a whole bunch of capacitors that detect how much charge was released.

  5. What does it detect? • A photodiode array is good for visible and ultraviolet radiation. Dr. Prushan’s Stolen Slides

  6. Advantages • Faster • More diodes • High S/N Ratio • Faster scan = less time for noise • More rugged/durable • No moving scanning part

  7. Advantage • Stray light not a problem hwe.oita-u.ac.jp/kiki/ronnbunn/paper_choi.pdf

  8.
