Abstract:Multi-spectral imaging is commonly used in biomedical field to detect and recognize targets, which are in a low contrast with their background. Highly integrated multichannel light-emitting diode (LED) devices enable tuning the spectral contents of the illumination in an accurate and compact fashion, and hence make multi-spectral lighting more easily achievable even in a microscope. Besides the light source, the light mixing system is also a key to realize it. Existing light mixing devices available for multi-… Show more
