An analytical optical approach—First-principle OPTical Intercept Calculation (FirstOPTIC)—
is developed for the optical performance evaluation of linear Fresnel collectors. Instead of …

No reliable in-situ optical characterization tool is available that can efficiently and accurately
measure various optical errors of individual heliostats in a utility-scale power-tower plant …

A new analytical method—First-principle OPTical Intercept Calculation (FirstOPTIC)—is
presented here for optical evaluation of trough collectors. It employs first-principle optical …

Power towers, a type of concentrating power tower technology, use a large number of
heliostats to concentrate sunlight and produce renewable energy. Optical errors of heliostats …

This paper introduces a novel technique to assess the alignment quality of heliostats in
operation. This technique combines theoretical imaging with aerial vision of an object …

Dish concentrators can produce highly concentrated flux for the operation of an engine, a
chemical process, or other energy converter. The high concentration allows a small aperture …

Concentrating solar power (CSP) can provide additional thermal energy to boost geothermal
plant power generation. For a newly constructed solar field at a geothermal power plant site …

The proper alignment of facets on a dish engine concentrated solar power system is critical
to the performance of the system. These systems are generally highly concentrating to …
