MEMS-FPI spectrum sensor MEMS-FPI spectrum sensor structure The MEMS-FPI spectrum sensor is composed of a MEMS-FPI tunable ﬁlter, photosensor (photodiode), and the like. It has a simple structure in which a MEMS-FPI tunable ﬁlter and photosensor is arranged on the same axis as the direction of the incident light. Though this product is a spectrum sensor, it uses a single-element photosensor and does not require an expensive multichannel photosensor.
