“Sample-Up-The-Ramp” (SUPR) and Non-Destructive Readout (NDR)

- In SUTR mode, each pixel is read multiple times during a single integration without resetting the accumulated charge. This non-destructive readout preserves the signal while providing several key advantages for high-precision imaging:

1. Extended Dynamic Range: Multiple reads capture signal before saturation, allowing accurate measurements even for bright sources.
2. Cosmic Ray and Noise Mitigation: Intermediate reads help identify and correct artifacts such as cosmic ray hits and Random Telegraph Noise (RTN).
3. Lower Effective Read Noise: Fitting a slope to multiple samples reduces noise by approximately the square root of the number of reads.
4. Rich Data for Analysis: Each read is stored as a slice in a 3D datacube, enabling advanced processing techniques like slope fitting and artifact correction.

Integration timeline and datacube structure

Non-destructive readouts during a single integration are shown as incremental signal measurements over time, starting from reset and idle states.
Each read is stored as a slice in a 3D datacube, enabling time sequenced data analysis for slope fitting and artifact correction.

Pixel ramp behaviors during integration

A cosmic ray hit introduces a sudden signal increase, dividing the ramp into two segments.
A pixel ramp reaching saturation; only unsaturated points (blue) are used to estimate the signal accumulation rate, while saturated points (red) are excluded. Each point represents a readout group.
