Photon Flux Modulation Results
✨ Overview
This Merge Request introduces photon_modulation.py, a new model that applies time-varying modulation to photon flux, compatible with CCD and CMOS simulation pipelines.
🔧 Technical Details
- New file:
pyxel/models/photon_collection/photon_modulation.py - Supports sinusoidal and square modulation types
- Uses exposure readout times for temporal variation
- Includes debug visualization for modulation curve
🧪 Testing
New YAML configuration for testing:
tests/test_photon_modulation.yaml🛰️ Integration
- Added model registration in
__init__.py - Updated
simple_collection.py,observation.py, andsimple_adc.py - Implements Issue #248
