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。

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 | |||
