AI Technical Summary
Conventional optical devices for capturing images from test strips suffer from poor illumination, leading to false results due to light scattering and reduced brightness, contrast, and hue, which hampers quantitative analysis.
A slab-based optical device system that uses multiple light sources and reflector elements to illuminate test strips, directing luminescence through slabs to prevent scattering and enhance image capture, combined with an imaging sensor to capture high-contrast images from both sides of the test strip.
The system provides accurate and error-free quantitative results by minimizing light scattering and enhancing image brightness and contrast, enabling precise analysis of analyte concentrations in biological samples.

Abstract
Description
[0001] SLAB-BASED OPTICAL DEVICE, SYSTEM, AND METHOD TO CAPTURE IMAGE OF TEST DEVICE
[0002] TECHNICAL FIELD
[0003] The present aspect relates generally to a medical device and more particularly to slabbased optical device, system, and method for capturing image(s) from a test device.
[0004] BACKGROUND
[0005] Test devices such as test strips are an apparatus that are used to measure any concentration of a chemical or some characteristics of a liquid.
[0006] Test strips are a simple, effective analytical tool used for the rapid detection of an analyte in the field or on-site. These test devices are subjected to detect any analyte and further generate a result on the test device. Such generated result is either visualized and analyzed by naked eye or by an optical detection device.
[0007] The results that are visualized by naked eye are qualitative and it provides the presence or absence of an analyte or any chemicals in the bodily fluids. The results that are visualized by optical detection device may be quantitative. The major limitations' associated with the conventional optical detection device are the false results due to the poor illumination. Such poor luminescence diminishes the picture of results in the test strip. The poor illumination also reduces the brightness, contrast, hue, saturation in the captured image. The camera may also flicker while capturing the image due to the poor luminescence, that results in failure in the quantitative analysis.
[0008] In some scenario due to the direct light that falls on the detection band may emit bright light after getting scattered from the liquid molecules on the track of the test strip. Such scattering of light may result in inaccurate results in quantitative analysis.
[0009] Thus, there is a need for a technical solution that overcomes the aforementioned problems of conventional optical device that have poor illumination to perform quantitative analysis on a result detected in the test strip. SUMMARY OF INVENTION
