资源简介:

Results of the Kinetix camera calibration (Photometrics, 01-KINETIX-M-C ). The two following modes were calibrated: "speed" (8-bits) and "sensitivity" (12-bits). Setup specifications: Excitation: Thorlabs collimated LED light source for microscopy No objective; instead, two diffusers are placed at this location (Thorlabs DG10-600-MD, 600 grit & DG10-120-MD, 120 grit) Dichroic: Semrock 146 Di01-R405/488/561/635 Imaging path: A 25.4 mm biconvex lens (Thorlabs LB1761-A) is positioned at the Fourier lens location; two diffusers are placed at the filter position (Thorlabs DG10-1500-MD, 1500 grit & DG10-220-MD, 220 grit) Acquisition parameters: for each mode, acquire 20,000 frames at 6 gradualy increased intensity levels, and 20,000 frames in the dark. Calibrate the full 3200x3200 pixels chip. Sensitivity mode: 10 ms exposure with 200 ms interval. Speed mode: 5 ms exposure with 90 ms interval. Analysis specifications: used the following software https://doi.org/10.5281/zenodo.10732470 Results: the results include for each mode: 1. pixel-dependent offset, variance, gain and read noise maps; 2. average offset, variance, gain and read noise; 3. regression curve used for estimating gain. Sensitivity mode results summary:The average offset: 100.692 +- 1.038 ADU countsThe average gain: 3.462 +- 0.098 ADU counts/photoelectronThe average read noise is: 1.288 +- 0.419 photoelectronsThe median read noise is: 1.139 photoelectronsThe RMS read noise is: 1.354 photoelectrons Speed mode results summary: The average offset is: 19.421 +- 0.723 ADU countsThe average variance is: 5.587 +- 2.673 ADU countsThe average gain is: 1.028 +- 0.154 ADU counts/photoelectron The average read noise is: 2.337 +- 0.916 photoelectrons The median read noise is: 2.225 photoelectronsThe RMS read noise is: 2.510 photoelectrons* ADU = analog-to-digital unit

Kinetix相机校准结果(Photometrics,01-KINETIX-M-C)。 本次针对两种工作模式完成校准:「速度模式(8位)」与「灵敏度模式(12位)」。 实验装置规格: 激发光源:采用索雷博(Thorlabs)显微镜用准直LED光源; 未配置物镜,取而代之的是在此位置安装两片漫射片(索雷博Thorlabs DG10-600-MD,600目;DG10-120-MD,120目); 二向色镜:Semrock 146 Di01-R405/488/561/635; 成像光路:将一枚25.4 mm双凸透镜(索雷博Thorlabs LB1761-A)置于傅里叶透镜位置;在滤光片位置安装两片漫射片(索雷博Thorlabs DG10-1500-MD,1500目;DG10-220-MD,220目)。 采集参数:针对每种模式,分别在6个逐级递增的光强等级下各采集20000帧,同时采集20000帧暗场图像。对整块3200×3200像素的芯片进行校准。 灵敏度模式:曝光时长10 ms,帧间隔200 ms。 速度模式:曝光时长5 ms,帧间隔90 ms。 分析规范:采用如下分析软件:https://doi.org/10.5281/zenodo.10732470。 校准结果涵盖两种模式的以下内容:1. 像素相关的偏移量、方差、增益与读出噪声分布图;2. 平均偏移量、方差、增益与读出噪声;3. 用于估算增益的回归曲线。 灵敏度模式结果汇总: 平均偏移量:100.692 ± 1.038 ADU(模拟数字单元,analog-to-digital unit) 平均增益:3.462 ± 0.098 ADU/光电子 平均读出噪声:1.288 ± 0.419 光电子 读出噪声中位数:1.139 光电子 读出噪声均方根值:1.354 光电子 速度模式结果汇总: 平均偏移量:19.421 ± 0.723 ADU 平均方差:5.587 ± 2.673 ADU 平均增益:1.028 ± 0.154 ADU/光电子 平均读出噪声:2.337 ± 0.916 光电子 读出噪声中位数:2.225 光电子 读出噪声均方根值:2.510 光电子 * ADU = 模拟数字单元(analog-to-digital unit)
