Imperceptible Calibration for Radiometric Compensation
, 2007 We present a novel multi-step technique for imperceptible geometry and radiometry calibration of projector-camera systems. Our approach can be used to display geometry and color corrected images on non-optimized surfaces at interactive rates while simultaneously performing a series of invisible structured light projections during runtime.

Advanced Electronic Materials, EarlyView.This work presents inkjet‐printed MHP photodetectors and optical filters. Three precursor inks enable bandgaps from 1.6–3.1 eV, covering the visible spectrum. Combining detector and filter produces a fully printed, dispersion‐free optical spectrometer with precisely tunable spectral selectivity and a minimum spectral bandwidth of 30 nm.

METHODS OF RADIOMETRIC CALIBRATION [PDF]
, 1962 Abstract : A general treatment of the calibration of optical instruments is presented which are to be used to measure electromagnetic radiation from sources of interest to the military services. The infrared spectral region is emphasized although the ultraviolet and visible wavelengths ar also treated.

The mechanism of labor in nonhuman primates: A look inside
The Anatomical Record, EarlyView.Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...
