1. Wide-field Imaging with Super-resolution Enabled by Raman Signals (WISERS)
Designed & developed at Swansea University with Dr. Deb Roy
Based on integration of Structured Laser Illumination (Digital Micromirror Device) and Fourier optics
~100 nm spatial resolution ; FHD 1080p (without interpolation) Raman/PL mapping
2. Multifunctional spectroscopy/optoelectronics set-up
Designed & developed at INST Mohali with Dr. Kiran Shankar Hazra and WITec team
Integration of elements like Supercontinuum laser source (fiber-coupled) for multi-excitation, Dark-field set-up for single-particle scattering spectroscopy, and Linkam temperature control system with conventional confocal Raman/PL microscopy set-up.
3. He-Cd laser (325 nm) based Photoluminescence spectroscopy set-up
Designed & developed at IIT Bombay with Prof. M. Aslam
Assembled with goal of research on wide-band gap semiconductors like ZnO/TiO2. Spectral resolution ~ 0.1 nm; Spectral range: 340 nm - 900 nm. Utilizes PMT as detector and improves SNR via inclusion of SRS Single Phase Lock-in Amplifier + Optical chopper.
4. Hyperspectral imaging system (Reflection/Transmission modes)
Designed & developed at Swansea University with Dr. Deb Roy
Macro-scale imaging (2 cm x 2 cm). Spectral resolution ~ 1 nm; Spectral range: 400 nm - 1700 nm.
