01
Fixed apertures
Interchangeable square and rectangular recessed openings provide the comparison. They do not change shape during a run.
CN-machine / Pre-gen v3
The first build.
A bench for questions.
A practical bridge from computational work to a physical aperture experiment. The design is digital; the apparatus has not yet been built or validated.
Make the comparison
possible to inspect.
The first bench brings together a light source to be characterized, interchangeable fixed apertures, a detector and its repositioning mechanism, and an existing computer.
Its purpose is to support a future comparison of transmitted light. Reliable measurements will depend on real geometry, illumination, wall behavior, detector collection and an uncertainty budget.
Inside the design
Parts with a purpose.
02
Detector movement
Guided repositioning supports alignment and planned scans. Travel, mounting and cable behavior still need physical checks.
03
Enclosure and access
An enclosure gives the setup a defined working space. Access for assembly, alignment and measurements remains part of the mechanical review.
The starting comparison
Same area.
Different shape.
Nominal geometry for discussing the first aspect-ratio pair. These dimensions do not replace a reviewed drawing, tolerances or characterization of manufactured parts.
| Feature | Square | Rectangle |
|---|---|---|
| Opening | 25 × 25 mm | 50 × 12.5 mm |
| Mouth area | 625 mm² | 625 mm² |
| Recess depth | 25 mm | 25 mm |
What happens
before a result?
Review the mechanical details.
Confirm interfaces, travel, clearances, fastening and access with the people making and assembling the parts.
Characterize the setup.
Measure the actual geometry, source and detector behavior. Check repeatability and unintended light paths.
Freeze the comparison.
Record the procedure, normalization, uncertainty budget and decision rule before evaluating the result.
Measure, then interpret.
Use the recorded uncertainties to decide what the physical comparison can and cannot establish.
