Overview

| --- |
|

This standard identifies the competences you need to align and set up holographic equipment for the production of a hologram, in accordance with approved procedures. You will be required to use appropriate drawings, specifications and test documentation to set up and align the various items of equipment. You will be expected to use the specified/appropriate techniques to carry out the setting up and production of the hologram in the correct sequence. The process will include alignment of the various shutters, lenses or spatial filters, mirrors and holographic plates, making adjustments to bring the settings within specification, and the final fixing of these components in their correct positions. You will need to use an optical power meter to measure the power density incident on the surface of the plate. You will need to work in the appropriate lighting conditions to avoid exposure of the plate during the setting-up phase.

Your responsibilities will require you to comply with organisational policy and procedures for the holographic setting-up activities undertaken, and to report any problems with the activities, components or equipment that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying setting-up and alignment techniques and procedures to produce a hologram. You will understand the hologram production system being set up and aligned. You will know about the setting-up and alignment techniques and procedures, test equipment and methods, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the hologram is produced to the required specification.

You will understand the safety precautions required when carrying out the holographic alignment and setting-up operations, in particular those relating to exposure to laser light. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.

  12. the properties of laser light which allows holograms to be produced both in mono-chromatic and colour form
  13. the need for a reference beam as well as an image beam to create the 3D image
  14. how to check/calibrate the test/alignment equipment to be used; or the organisational procedures for ensuring that the equipment is maintained and correctly calibrated
  15. how to conduct any necessary checks/tests to ensure the integrity, functionality, accuracy and performance of the holographic system and its dependences
  16. how to recognise defects
  17. how to interpret the alignment/test readings obtained, and the significance of the readings
