Note: the following is a brief summary of the subject matter contained in the paper published under “6441-09, Session 1” of Photonics West Conference 6441, under the title quoted above. For a more accurate and detailed representation, please consult the paper itself.

Researchers at the Cancer Imaging Department of the BC Cancer Agency, Vancouver, BC, produced a series of hyperspectral transmission images of hematoxylin and eosin stained tissue sections from cervical biopsies, images of maximum contrast were achieved via custom software that provided extraction of spectra at each pixel. This allowed for determination of selected features and differentiation of tissue features.

Using a spectrally and temporally programmable light engine, illumination profiles were achieved via a spatial light modulator – dynamically creating any narrow or broadband spectral profile. This allowed for the selection of particular illumination wavelengths. Images were captured by a monochrome CCD camera, with several methods employed to combine images from individual and composite spectral bands to recreate color images for pathologist review.

Of note, the light engine provided for digital control of all illumination parameters – integrating the lamp, wavelength control, intensity control and exposure control in a Micro Electro Mechanical Structure (or MEMS) based system.

BCCA researchers also captured hyperspectral Images of cervical tissue sections stained with molecular specific stains and hematoxylin and processed them, using spectral unmixing techniques to enhance contrast between tissues labeled with the molecular stain and surrounding tissues.

A major departure from filter wheels, filter changers and, most importantly, expensive optical filters currently in use, OneLight Spectra represents a major evolution in digital light engine technology – making it possible to instantly control the spectrum, intensity and duration of light via software, replacing the limiting, costly and time-consuming process of sourcing multiple hardware components to achieve specific illumination needs.

“Having thoroughly tested OneLight Spectra for a number of applications with research and clinical partners, we couldn’t be more pleased by the results” says Nick Mackinnon – President, CEO and Founder of OneLight. “What we have here is a cost-effective, Spectrally Programmable Light Engine that will grant researchers and healthcare professionals the power to control light precisely, instantly and dynamically – a freedom they’ve never had before.”

OneLight looks forward to demonstrating their OneLight Spectra at BIOS booth #8643 and Photonics West, South Hall booth #6293.
