Spectral Photography

Broadband ringdown spectral photography.

A new technique that enables frequency-resolved cavity ringdown absorption spectra to be obtained over a large optical bandwidth by a single laser shot is described. The technique, ringdown spectral photography (RSP), simultaneously employs two key principles to record the time and frequency response of an optical cavity along orthogonal axes of a CCD array detector. Previously, the principles ...

Practical Spectral Photography

We introduce a low-cost and compact spectral imaging camera design based on unmodified consumer cameras and a custom camera objective. The device can be used in a high-resolution configuration that measures the spectrum of a column of an imaged scene with up to 0.8 nm spectral resolution, rivalling commercial non-imaging spectrometers, and a mid-resolution hyperspectral mode that allows the spe...

Computational Photography: Epsilon to Coded Photography

Computational photography combines plentiful computing, digital sensors, modern optics, actuators, and smart lights to escape the limitations of traditional cameras, enables novel imaging applications and simplifies many computer vision tasks. However, a majority of current Computational photography methods involves taking multiple sequential photos by changing scene parameters and fusing the p...

Computational Photography

Computational photography is an emergent multidisciplinary field that combines topics in optics, computer graphics, image and signal processing. The objective is usually the development of new algorithms or systems to capture images overcoming the limitations of conventional techniques. Images are not simply captured as 2D projections of a scene, they are rather coded before reaching the sensor...
