Interactive Analysis Instructions:
Line Tool (Handles A & B): Drag these nodes to align with the axis of your diffraction pattern. The intensity profile along this axis will plot dynamically in the chart below.
Color Picker (Handle Picker): Move this reticle to a reference color area of the diffraction beam (e.g. peak central spot). The selected color will determine the baseline/channel for intensity mapping.
Calibration Ruler (Handles C1 & C2): Position this ruler over a known physical dimension in your image, input its actual length (in mm) in the sidebar, and click Set to calibrate the scale.
💡 Tips for Capturing Good Photos for Analysis:
Align Camera Parallel: Keep the camera sensor strictly parallel to the projection screen to prevent perspective distortion.
Avoid Sensor Saturation: Reduce the exposure or laser power. If the central peak is clipped at pure white (255, 255, 255), the true peak intensity shape is lost.
Minimize Ambient Light: Take photos in a dark room to maximize the contrast of weak side-lobes (secondary maxima) against the dark background.
Keep Camera Stable: Use a tripod or a mounting stand to eliminate motion blur during capture.
Include a Physical Ruler: Place a physical ruler in the same projection plane to make calibration straightforward.
