Presentation

Hola! Welcome to my blog!. I am a physicist and pursuing a doctoral research project where I explore the intersections of atmospheric radiative phenomena and advanced imaging techniques. My academic background spans atmospheric physics and biomedical physics, with a specific focus on the structural formation of atmospheric ice and the non-invasive imaging. I am a deeply hands-on experimentalist who loves building instrumentation setups, operating complex lab equipment, and conducting fieldwork. I pair this practical mindset with robust skills in data analysis and numerical tools. Ultimately, I am interested in how optics and instrumentation can be applied to radiation physics, and remote sensing across our atmosphere, hydrosphere and land.

Full-Spectrum Camera Composites

Unlocking the Hidden Spectrum: Building Custom Composite Imagery with Full-Spectrum Photography Exploring multi-spectral imaging by mapping Infrared Ultraviolet reflectance images into false colors using a modified reflex camera. Have you ever wondered what the world looks like beyond what human eyes can see? By default, our eyes (and standard digital cameras) are locked into the narrow strip of visible light spanning roughly 400nm to 700nm. But with a modified full-spectrum reflex camera , that boundary disappears. By removing the internal IR/UV cut filter from the camera sensor, the full range of light—from ultraviolet (UV) all the way to near-infrared (IR)—becomes available to capture.

Mapping the Invisible: UV and IR Channels When shooting multi-spectral scenes, translating invisible light into a recognizable color image requires a custom ...

UVF Photogrammetry

UV Fluorescence Fluorescence occurs when a substance absorbs light or other electromagnetic radiation and emits it back almost instantaneously. When this process is triggered by invisible Ultraviolet (UV) light , it is called UV fluorescence. UVF When UV photons strike fluorescent atoms, electrons absorb the energy and jump to a higher, unstable energy state. As they cascade back down to their ground state, they lose a small amount of energy as heat and release the remaining energy as a new photon. Check this photo of a scorpion> Because some energy is lost, the emitted photon has less energy than the absorbed one. In physics, less energy means a longer wavelength , shifting the light from the invisible UV spectrum into the visually striking, glowing colors of the visible spectrum. The Stokes Shift Relationship: $$\Delta \nu = \nu_{absorbed} - \nu_{emitted}$$ Where $\Delta \nu$ repre...
