Sensing apparatus having rotating optical assembly

摘要: An apparatus for optical sensing of samples includes an source, assembly being rotatable about axis, a sample holder, and detector. The rotates, allowing the to sense results from plural locations on without moving sample. Moving in linear direction while rotating allows entire containing multiple test sites, such as biochip. mirrors direct light source is provided. Preferably, enters along axis rotation. Sensing methods consistent with invention are also described.
