Non-destructive read (NDR) mode

DaVinci CMOS imagers can be read non-destructively without resetting the pixels. Thus the pixels can be read repeatedly to reduce noise, or the frame rate can be doubled with any image frame serving as the reset frame for a subsequent image frame. This allows post-acquisition framing of fast events. By contrast, CDS imaging resets the pixels every frame and can cause events to be randomly split between frames as shown below.

DaVinci 2K NDR Non Destructive Read


For STORM imaging, DaVinci CMOS imagers are run in a windowed mode at high frame rates. 2048×180 pixels at 2500 Hz is typical, acquiring 10,000 frames in 4 seconds. The imager is reset once every 500 frames. Sample drift and bleaching are greatly reduced.
Flashes are oversampled and both reset and image frames are optimally selected POST-ACQUISITION to maximize SNR and minimize background.
With slower EMCCD cameras, flashes can begin and end at any time within one or two adjacent frames adding to the uncertainty of when the flash occurred. The signal can be randomly split between frames, reducing the SNR.

Ideal for Super Resolution

•On-Chip Binning – faster frames, deeper wells
•Low Read Noise – 2.8 e- without correction
•High QE – 65% without microlenses
•No microlenses – no distortion, crosstalk
•Monotonic – no A/D stitching
•NDR Mode – 2X faster, optimal sampling

Ideal for Storm

•Much higher frame rates than EMCCDs
•10,000 frames in 4 second instead of minutes
•Accommodates faster flash rate
•Less laser supression means less bleaching
•Greatly reduced sample drift
•NDR Mode – 2 x SNR, > 3 x events per time period
