    • A vein-image-enhancing system transmits two different wavelengths of laser light, being directed by a steering means, to form a raster pattern on a target. Reflected light comprises a contrasted image formed by a portion of the first wavelength being absorbed by veins, and a portion of that first wavelength being reflected from the target. A photodectector sensitive to the first wavelength captures reflected light. The contrasted image is projected onto the target to illuminate vein locations using the second wavelength, which comprises visible light. Projection may operate according to one of three modes: the alternating frame mode, a dual buffer mode, and real time mode. The AFM and DBM modes incorporate analog to digital converters and digital memory for timed projection onto the target. The vein enhancer may be specially attached to different platforms—hospital bed, IV stand, wheelchair, etc., to enable convenient use of the enhancer on a patient.
    • 静脉图像增强系统通过转向装置传输两种不同波长的激光,以在目标上形成光栅图案。 反射光包括由静脉吸收的第一波长的一部分形成的对比图像,并且该第一波长的一部分从目标物反射。 对第一波长敏感的光电探测器捕获反射光。 使用包括可见光的第二波长将对比图像投影到目标上以照亮静脉位置。 投影可以根据三种模式之一操作:交替帧模式,双缓冲模式和实时模式。 AFM和DBM模式包含模数转换器和数字存储器,用于定时投影到目标上。 静脉增强剂可以特别附着在不同的平台上 - 医院病床,IV支架,轮椅等,以便于使用患者上的增强剂。
