Machine Learning-Based Rapid Diagnostic-Test Reader for Albuminuria Using Smartphone

Ritambhara Thakur;Prateek Maheshwari;Sudip Kumar Datta;Satish Kumar Dubey;Chandra Shakher

IEEE Sensors Journal
Year: 2021 | Volume: 21, Issue: 13 | Journal Article |
Cited by: Papers (18)
Albuminuria is an excellent marker for early diagnosis of kidney and cardiovascular disease. Urine dipsticks that are widely used for rapid screening of albumin, lack sensitivity and specificity in lower concentrations (<300 mg/dL) which is clinically very significant for early diagnosis and often provide qualitative or semi-quantitative results. Precise quantification of lower concentrations is b...Show More

Development of Smartphone-Based Lateral Flow Device for the Quantification of LH and E3G Hormones

Ritambhara Thakur;Faiz Akram;Vivek Rastogi;Amit Mitra;Rahul Nawani;Varun Av;Satish Kumar Dubey;Chandra Shakher

IEEE Sensors Journal
Year: 2020 | Volume: 20, Issue: 23 | Journal Article |
Cited by: Papers (9)
Hormone levels of urinary luteinizing hormone (LH) and Estrone-3-gluconoride (E3G) are key indicators to control reproductive health conditions of women. An “Inito” device is developed for the lateral flow measurement and is coupled to a smartphone to predict the fertile window by providing a precise estimation of the concentration of these hormones. The image acquisition and data analysis softwar...Show More

Testing of micro-optics using digital holographic interferometric microscopy

Varun Kumar;Chandra Shakher

2016 4th International Conference on Photonics, Optics and Laser Technology (PHOTOPTICS)
Year: 2016 | Conference Paper |
Digital holographic interferometric microscopy (DHIM) is used as metrological tool for the testing of micro-optics. The paper presents the measurement of sag height (h), radius of curvature (ROC), and shape of micro-lens. The advantage of using the DHIM is that the distortions due to aberrations in the optical system are avoided by the interferometric comparison of reconstructed phase with and wit...Show More

Transmission Mode Full-Field Swept-Source Optical Coherence Tomography for Simultaneous Amplitude and Quantitative Phase Imaging of Transparent Objects

Tulsi Anna;Vishal Srivastava;Chandra Shakher;Dalip Singh Mehta

IEEE Photonics Technology Letters
Year: 2011 | Volume: 23, Issue: 13 | Journal Article |
Cited by: Papers (5)
A transmission mode full-field swept-source optical coherence tomographic system is demonstrated for simultaneous amplitude and quantitative phase imaging of transparent objects. The experimental setup consists of a swept-source system, fiber-optic Mach-Zehnder interferometer, and an area detector. By means of sweeping the wavelength of light source, multiple interefrograms were recorded and both ...Show More

Real time monitoring of vibrations using interferometric sensor

C. Shakher;A.L. Vyas;A. Seth

Proceedings of ICICS, 1997 International Conference on Information, Communications and Signal Processing. Theme: Trends in Information Systems Engineering and Wireless Multimedia Communications (Cat.
Year: 1997 | Conference Paper |
Cited by: Papers (1)
An interferometric sensor for monitoring the localised strains and vibrations is presented. The modified Michelson interferometer is employed to process the signal received from the sensing interferometer. Details of the sensor amplifier and signal processing scheme which can provide real-time monitoring of surface vibrations (amplitude, frequency and direction of motion) are also presented.Show More
