Abstract

Standard-of-care endoscopy and laparoscopy require multiple cameras to enable molecular imaging, which leads to challenges of 3D image registration and overlay. To address this, we are developing a targeted multispectral imaging (MSI) camera using custom multispectral filter arrays integrated onto image sensors. The design augments RGB-Bayer filters with sub-pixel narrowband filters, thereby maintaining white-light imaging through pixel binning while adding MSI contrast enhancement. Prototypes were tested by imaging tissue-mimicking phantoms containing blood of varied oxygenation, ICG dye and color charts. Future work will examine the translation potential for chip-on-tip endoscopy.
