Devices and systems are disclosed for characterizing a target at an intravascular location based on detection of reflected light, where the detected reflected light intensity is measured at each wavelength or range of wavelengths of a set. At least one ratio between the detected reflected light intensities is determined, including at least one ratio between the reflected light intensities of at least two discrete wavelengths or ranges of wavelengths. Based on the at least one ratio, a type and/or composition of the target at the intravascular location can be determined. This provides a simple analysis system as compared to full spectroscopic analysis. 公开了用于基于对反射光的探测来表征血管内位置处的目标的设备和系统，其中，在集合的每个波长或波长范围下测量探测到的反射光强度。确定探测到的反射光强度之间的至少一个比率，包括至少两个离散的波长或波长范围的反射光强度之间的至少一个比率。基于至少一个比率，能够确定血管内位置处的目标的类型和/或成分。与全光谱分析相比，这提供了简单的分析系统。
