Physiological Effects of Radiant Energy (Laurens, Henry)

Some Effects of Radiant Energy in Relation to Etiolation.

Numerous investigators have worked on the problem of determining the effect of small quantities of visible radiant energy on seedlings and other plants with stored foods. The literature is extensive and goes back over one hundred years. MAcDOUTGAL (6) has thoroughly reviewed the work before 1900 while TRUMPF (9) and BURKHOLDER (1) have reviewed this and much of the later work. The work before 1...

Radiant Energy and the Eye

Ophthalmology Series. (Pp 321, Figs 167, Tables 41. £25.00). London: Bailliere Tindall, 1980. THIS well presented and well organised book discusses the known and potential effects and hazards of radiant energy on the eye. It admirably correlates current scientific knowledge concerning radiant erergy with its biological effects on ocular structures and documents the various mechanisms whereby v;...

A physiological plant growth simulation engine based on accurate radiant energy transfer

We present a new model for plant growth simulation, taking into account the ecophysiological processes driving plant development with unprecedented fidelity. The growth model, based on a physiological analysis, essentially simulates the internal function of the plant, and has been validated against measured biological data with excellent results. We show how to account for the influence of ligh...

Measurement of Radiant Energy in Light Therapy

Radiant energy required for infrared neural stimulation

Infrared neural stimulation (INS) has been proposed as an alternative method to electrical stimulation because of its spatial selective stimulation. Independent of the mechanism for INS, to translate the method into a device it is important to determine the energy for stimulation required at the target structure. Custom-designed, flat and angle polished fibers, were used to deliver the photons....
