Abstract: Preparing and analyzing a fluid for a multi-spectral analysis is disclosed. The multi-spectral analysis includes providing two or more separate and independent types of spectroscopies including at least a first spectrometer and a second spectrometer of a spectrometer system to examine the fluid after that fluid has passed through one or more sample preparation processes to increase a purity of a target biological entity in the fluid and thereby enhance signal to noise ratios in measurements and related data analysis operations.

Abstract: A Raman spectroscopy based system and method for examination and interrogation provides a method for rapid and cost effective screening of various protein-based compounds such as bacteria, virus, drugs, and tissue abnormalities. A hand-held spectroscope includes a laser and optical train for generating a Raman-shifting sample signal, signal processing and identification algorithms for signal conditioning and target detection with combinations of ultra-high resolution micro-filters and an imaging detector array to provide specific analysis of target spectral peaks within discrete spectral bands associated with a target pathogen.

Abstract: The present disclosure describes devices and techniques for testing. In particular, the disclosure describes testing systems that are portable and easy to operate. The testing system can include a measurement apparatus that can be used to measure spectral characteristics of a sample and can be in a portable, hand-held form-factor. The testing system also includes a computing device, such as a mobile phone, a laptop, or a personal computer that can communicate with the measurement device over a wired or a wireless communication link and also can have form-factors that are portable. The computing device can run applications or programs that receive spectral data of the sample from the measurement apparatus and can process the received spectral data to determine various properties of the sample. As both the measurement apparatus and the computing device are portable, the measurements can be easily made at site where the fluid is produced.

Abstract: A system for fluorescence-based imaging of a target includes at least one excitation light source configured to emit a homogeneous field of excitation light and positioned to uniformly illuminate a target surface with the homogeneous field of excitation light during fluorescent imaging, a power source, and a portable housing configured to be held in a user's hand during imaging. The housing contains a lens, a filter, an image sensor, and a processor. The filter is configured to permit optical signals responsive to illumination of the target surface and having a wavelength corresponding to at least one of bacterial autofluorescence and tissue autofluorescence to pass through the filter to the image sensor. The at least one excitation light is adjacent to the housing so as to be positioned between the target surface and the image sensor during fluorescent imaging.
