Presentation Transcript

  1. 1288 Standard - Basic Information Dr. Emil Ott, PCO AG

  2. Overview ?

  3. Vendor, Model • vendor • warranty, address, website etc. • model • identification, selection, comparison

  4. type of data presented • typical • guaranteed • guaranteed over life time The type of data may vary for different parameters. E.g. guaranteed specification for most of the parameters and typical data for some measurements not easily done in production (e.g. h(l) = QE). It then has to be clearly indicated which data is of what nature. Type of Data

  5. MV-13 KAI 2001 Sensor Type • sensor type • CCD • CMOS • CID • Hybrid • other

  6. 1cm sensor diagonal & lens category in inch 1392 x 1040 pixel2/3" lens category ...in case of a line sensor the length should be given. 1280 x 1024 pixel1.2" lens category Sensor Diagonal & Lens Category {graphics from: Optical Microscopy Primer}

  7. theoretical limit of axial resolution limit (MTF): pixel size 7.4µm: MTF = 67.6 [line pairs / mm] pixel size 3.45µm: MTF = 145 [line pairs / mm] ...if the pixel repetition rate equals the length of the pixel {graphics from: Optical Microscopy Primer} Resolution & Pixel Size

  8. {graphics from: Optical Microscopy Primer} Readout Type & Transfer Type (CCD only) • readout type • progressive scan • interlaced scan • transfer type • interline transfer • frame transfer • full frame • frame interline transfer

  9. Shutter Type (CMOS only) • shutter type • rolling shutter • global shutter • non shutter • other

  10. Overlap Capabilities • overlap capabilities • overlapping: readout of frame n and exposure of frame n+1 can happen at the same time • non-overlapping: readout of frame n and exposure of frame n+1 can only happen sequentially • others: defined in the data-sheet

  11. Frame Rate @full frame Maximum frame rate at the given operation point (no change of settings permitted).

  12. General Conventions • general conventions • conditions, which are all the same for all or many measurements (e.g. wavelength, which has been used for measurements) • conventions, which are all the same for all or many measurements (to be specified)

  13. Definition used for Typical Data number of samples, sample selection, tolerances, etc...

  14. Other... interface types, camRAM, etc...

  15. Conclusion... • The basic information data are a minimum requirement to compare image sensors and camera systems. They should enable a pre-selection for products, which are subsequently compared in more detail. • The more detailed comparison with 1288 data is explained in the next presentation... Thank you for your attention!
