文摘

Apps have been used for providing additional user functionality on demand to the smartphone. Several highly promising medical apps have been introduced that rely on the build-in camera. However, some of these apps fall short of the expectations, due to the inherent limitation of the camera to operation in the visible spectral range. The more detailed spectral information that an optical microspectrometer can offer is needed. Although CMOS-compatible MEMS technologies enable the on-chip integration of the microspectrometer with the CMOS camera, implementing such a step would result in a device that would be considered a customized unit within a universal platform. Consequently, the economic viability would depend on the added value of the microspectrometer in popular applications versus the intrusion of the microspectrometer-specific processing on the imager fabrication. The LVOF-based microspectrometer is introduced as a CMOS-compatible concept to meet the challenges imposed by the high production volume that is characteristic for the smartphone. The state-of-the-art of both the interactive optical app and the LVOF-based microspectrometer are presented.
