We suggest to use a combination of optical tweezers and single-image quantitative differential interference contrast (DIC) emulated by a spatial light modulator (SLM) to study physiological shape changes in thrombocytes after activation and demonstrate the effectiveness of this system for the given task. A specially designed phase mask displayed at the SLM enables quantitative phase calculation from only a single recording. The optical tweezers stabilize trapped thrombocytes for long-time monitoring of changes in the optical thickness profile of thrombocytes during activation by adenosine diphosphate (ADP).
我们建议使用光学镊子和由空间光调制器 (SLM) 模拟的单图像定量差分干涉对比 (DIC) 的组合来研究激活后血小板的生理形状变化,并证明该系统在给定任务中的有效性。SLM 上显示的特殊设计的相位掩模仅从单个记录即可进行定量相位计算。光学镊子稳定捕获的血小板,以便在由二磷酸腺苷 (ADP) 激活期间长时间监测血小板光学厚度轮廓的变化。
