The drive controlling apparatus has a memory of storing preset drive information of each of the optical adjusting members, and a controller for performing a preset drive control for controlling the drive of each of the optical adjusting members on the basis of the preset drive information. Various embodiments provide catheter-based spectroscopic systems that are configured to cycle between different optical interrogation techniques such as Raman spectroscopy, optical coherence tomography and time-resolved laser-induced fluorescence spectroscopy. The coating preferable has high emissivity. Further, the first and second consumer product packages are different. The magnetic tunnel junction element is disposed between the bit line and the selection transistor and is electrically connected to the bit line and the selection transistor, wherein the first and second free layers have substantially different switching currents.
