Integrated Spectrometers for Spectral Tissue Sensing

Minimally-invasive image-guided procedures – such as taking biopsies in screening suspicious nodules for cancerous tumors – are becoming increasingly important in clinical practice. Real-time tissue-characterization feedback during a surgical intervention can greatly reduce false negatives, significantly improve the outcome of diagnosis and treatment, and reduce the cost of oncology treatment.

In order to distinguish different types of tissue a high sensitivity over a broad spectral range is required, which is currently only possible by combining bulky and costly spectrometers. The InSPECT project aims at developing and integrating photonic building blocks for a new class of low-cost miniaturized spectral tissue sensing devices. The most promising approach for miniaturization is photonic integrated circuit (PIC) technology platforms.

Fraunhofer IZM forms part of InSPECT and supports it at the development of a functional, low-cost nanospectrometer packaging that includes fiber optic interconnections.

This project is funded by Horizon 2020 within the programme ICT-26-2014: Photonics KET, Research and Innovation Action, project "InSPECT" with a grant agreement number of 644483.
