• orientation of all cameras in optical metrology should be always the be the same
• order of measured points should be always the be the same

Why? We have to unambiguously map panels in optical metrology and in data from DAQ. Different detector orientation or different order of measurement need in special treatment in the processing script, which is error-prone and always needs in verification.

...

• orientation of camera should be consistent with its beam-view in hatch, quad Q0 in the top left corner.
  
  • orientation of quad labels should be human readable (from left to right) in hatch position;
    on current photo labels need to be rotated upside-down (right . Right photo shows how embarrassing labels look in the hatch).
  • add labels for vector of gravity or x-y for optical metrology in order to exclude wrong orientation
  • microscope origin should stay the same during the measurements. 
    Origin location does not matter,  but it can optionally be labeled somewhere for uniformity of metrology data. 

Measurement order

• measurement order of points per quad should be done in style of Chris Kenney, as shown on photo.microscope origin location does not matter, but can be labeled somewhere for uniformity of metrology data, clock-wise order for panels and corners, beginning from bottom-left.
• metrology data is saved in spreadsheets xlsx or text format.
• units - signed micrometers, without decimal dot.
• example of data:

...

• All labels on detector connectors and cables should show THE ONLY WAY to connect camera in hatch.

Summary

• Engrave detector name on camera body.
• Add labels for unambiguous detector orientation:
  • vector of gravity,
  • x-y (and optional origin) for optical metrology,
  • all labels should be left-to-right readable in hatch (now for 2M.0 they are upside-down).
• Use the same detector orientation in optical metrology, Q0 is in upper left corner in microscope x-y Cartesian frame. Origin location does not matter.
• Use the same order of measuring points per quad, as numerated on photo.
• Connect camera connectors to Plug-in properly labeled cables to the properly labeled cables camera connectors.
