In this paper, we introduce the concept of hyperlines in light fields. When represented by the two-plane parameterization, hyperlines are 2-Degree-of-Freedom (2-DOF) linear entities in the 4-D light field. The light field can be thought of as a dual space of the world space. In this dual space, cameras appear as hyperlines with heterogeneous colors which we call camera hyperlines (CHL), while s...
Fringe projection profilometry has been intensively studied for several decades. However, due to the limitation of field range a single projector, when measuring objects with complex surfaces, there are always shadow areas in captured images, resulting missing measurement data dark areas. To solve this problem, systems double projectors and camera were employed. Not only reduced, but system rec...
Light spectrum plays a key role in the biology of symbiotic corals, with blue light resulting in higher coral growth, zooxanthellae density, chlorophyll a content and photosynthesis rates as compared to red light. However, it is still unclear whether these physiological processes are blue-enhanced or red-repressed. This study investigated the individual and combined effects of blue and red ligh...
Plant photoreceptors that regulate photomorphogenic development include red/far-red-light-absorbing phytochromes and blue/UV-A-light-absorbing cryptochromes. We have undertaken a genetic screen to identify additional components downstream of the photoreceptors in Arabidopsis thaliana. We identified a short hypocotyl mutant under red and blue light, hypersensitive to red and blue 1 (hrb1). Mutat...
A red/purple coloration of lower (abaxial) leaf surfaces is commonly observed in deeply-shaded understorey plants, especially in the tropics. However, the functional significance of red abaxial coloration, including its role in photosynthetic adaptation, remains unclear. The objective of this study was to test the back-scatter hypothesis for abaxial leaf coloration, which posits that red pigmen...
Photomorphogenetic responses have been studied in a cucumber (Cucumis sativus L.) mutant (lh), which has long hypocotyls in white light (WL). While etiolated seedlings of this mutant have a similar phytochrome content and control of hypocotyl elongation as wild type, deetiolation is retarded and WL-grown seedlings show reduced phytochrome control. Spectrophotometric measurements exhibit that WL...
This paper presents both, the design and the development of a monitoring and control system via web for a closed microalgae crop and the results that were gotten using the strain Haematococcus pluvialis. The research was done at Sabana University (Colombia) and it aims to quantify the kinetic growth associated to the increment of biomass and the development of red pigment inside the cells when ...
