OCT用线阵高速扫描相机 OCTOPLUS
产品描述
e2v 宣布推出e2v OCTOPLUS, 这是一个用于光学相干断层扫描（OCT）和通用光谱学的模块化线性CMOS相机平台。
在过去的十年中，e2v一直在为OCT和通用光谱分析应用交付先进的线性CCD相机。CCD技术具有一定的速度限制和灵活性限制，因此e2v开发了新的基于CMOS的OCTOPLUS相机模块，该模块可大幅提高扫描速度（在12位中达到130 kA-scan / s）。这代表着重大的飞跃，并改善了功能成像质量，从而有利于诸如血管造影等应用。
e2v’s OCTOPLUS相机模块以极具吸引力的价格并结合了高速，易于对准，高信噪比，易于USB3接口和可定制处理的特点。OCTOPLUS不仅是标准规格产品，用户可以自由选择速度，像素高度，满井容量，接口和传感器封装，提供60多种相机组合。这使光学工程师能够设计其特定的OCTOPLUS摄像机，使其非常适合其 光谱仪，每种选件在特定条件和设置下均具有特定优势。它还允许客户仅选择他们感兴趣的选项/功能来控制成本，以更好地满足其目标售价。

编号方式
相机具有不同的传感器版本和速度。相机部件号如下所述. 以下USB camera (UB) 以供参考，并可访问此处未提及的不同速度。
Package
Material used to connect the silicon chip with the electronics board.
Sensor package is correlated to alignment precision (flatness, rotation and tilt) & robustness to temperature changes.
C
Ceramic
High precision alignment and robust to temperature changes
S
Organic
Moderate precision alignment, but cost optimized
Interface
Camera interface to be chosen according to speed required and system complexity
C
L
Camera Link
Enables quick demonstration & testing, enables to reach the highest
speed (up to 250KHz)
U
B
USB3
Optimizes system cost by removing the need for frame grabber component. Limited to 130KHz speed because of USB3 data throughput
limitation
Pixel height
Pixel shape is rectangular to help alignment and increase tolerance to T° changes
0
20 µm
Medium pixel height- optimize energy capture in defocused edges
relatively to a 10µm square pixel.
2
200 µm
Large pixel height - remove the need for active alignment & calibration
Pixel full well capacity
Pixel converts photons into e- and stores then during integration time.
The maximum amount of e- stored in the pixel is named the full well capacity. Higher full well allows higher SNR
A
140 ke-
Standard pixel full well capacity
B
200 ke-
High pixel full well capacity for high SNR level in standard B-scans
Sensor / camera speed
Several sensor speed versions are available to enable choosing the best price vs performance ratio.
Higher speeds allow fastest scan rate to increase Cube/Window size Lower speeds cameras optimize costs
