Abstract

Using a digital micromirror device (DMD) coupled to two array sensors, we have set up a compact modular system that enables a region of interest of an object to be targeted using a quasi-one-dimensional or point-like characterization device. The system acts as an optical compressor, reducing the amount of data needed to analyze a region of interest of the object under test. At the aim of applying this approach for the spectral characterization of the eye, a spectrometer is used to carry out spectral measurements of the selected region of interest. The results presented have enabled us to validate the proof of concept of our system with preliminary tests on ex-vivo corneas. Applications in the field of ophthalmology are foreseen and being studied for early diagnosis of eye diseases.
