How to use a multi-wavelength light source for remote monitoring
Using multiple LEDs and PDs in a multiplexed configuration achieves multiwavelength measurements and monitoring. There is a growing interest in photoplethysmography (PPG) for the continuous monitoring of cardio-respiratory signals by portable instrumentation aimed at the early diagnosis of cardiovascular diseases. In this context, it is conceivable that PPG sensors working at different wavelengths. Mightex WFC-series multi-wavelength fiber-coupled light sources are enabled by the latest LED technologies, and Mightex's proprietary beam combining and coupling optics. Up to eight (8) LEDs are coherently combined into a single multi-mode fiber with the highest efficiency practically possible. Combined with Ayar Labs TeraPHY™ optical I/O chiplet, the solution provides 5x-10x higher bandwidth, 10x lower latency, and is 4x-8x more.
