Optoelectronic modules operable to measure proximity independent of object surface reflectivity and, in some implementations, operable to measure characteristics (such as surface reflectivity or absorptivity) of stationary or moving objects are disclosed. The optoelectronic modules are operable to determine, for example, pulse rate, peripheral blood circulation, and/or blood oxygen levels of moving objects, such as the appendage of a user, in some instances. The optoelectronic modules can be used to measure peripheral blood circulation, for example, when a user of the optoelectronic module isengaged in physical activity, such as walking, running or cycling. 公开了可操作以独立于物体表面反射率来测量接近度，并在一些实现方式中可操作以测量静止或移动物体的特性(诸如表面反射率或吸收率)的光电模块。例如，在一些实例中，光电模块可操作以确定诸如用户的附肢之类的移动物体的例如脉搏速率/外周血液循环和/或血氧水平。例如，光电模块可用于在光电模块的用户从事诸如步行、奔跑或骑车之类的身体活动时测量外周血液循环。
