          Abstract

          Resumen: La medición espectral multi-angular de la vegetación requiere de sistemas goniométricos costosos y pesados, difíciles de operar en condiciones de campo y laboratorio. Para facilitar este tipo de mediciones, se diseñó un sistema goniométrico (SIGO-CP) simple de operar y de bajo costo, lo suficientemente flexible para ser usado en campo y laboratorio. El SIGO-CP, a diferencia de los sistemas actuales, tiene tres grados de libertad en vez de dos: acimutal, cenital y radial, permitiendo cambiar el área asociada al efecto de escala de las observaciones. El SIGO-CP fue ejemplificado en su implementación bajo condiciones de laboratorio, incluida la aplicación de eventos de precipitación con un simulador de lluvias, para experimentos de arreglos geométricos de especies vegetales en bolsas de plástico sobre las que se utiliza un fondo de suelo a la altura de los inicios de los tallos de las plantas.

          Abstract: The multi-angular spectral measurement of vegetation systems requires expensive heavy goniometers, difficult to operate in field or laboratory. To facilitate these measurements, we designed an inexpensive goniometric system (SIGO-CP), which is simple to operate and flexible enough to be used in field or laboratory. The SIGO-CP, unlike current systems, has three degrees of freedom instead of two: azimuthal, zenithal and radial, which permits changing the area of the field of vision associated with the scale effect of the observations. Implementation of the SIGO-CP was demonstrated under laboratory conditions, including application to rainfall events with rainfall simulator for experiments in geometric arrangements of plants in plastic bags over a table with plant stems above soil cover.
