CONCEPTO DE PSFCONCEPTO DE PSF Point Spread Function, Función de Difuminación

del Punto , es la forma de reproducir un punto para una muestra optica, dicho punto se deformara dependiendo del sistema. Dicha funcion seria un PUNTO para un sistema optico perfecto.

TENEMOS UNA PSF PARA CADA SISTEMA OPTICO Cada elemento en el camino optico la modifica

Objective Cover slip Sample

La cantidad de luz detectada (por el ojo, la CCD o el fotomultiplicador) es inversamente proporcional al cuadrado de la magnificación.

MX SEÑAL

La cantidad de luz detectada (por el ojo, la CCD o el fotomultiplicador) es directamente proporcional a la apertura numérica (NA).

N.A. SEÑAL

Ergo, para experimentos de baja luminosidad usar lentes de baja magnificación y alta NA (p.ej. 60X aceite 1.42)

CONFOCAL DSU and WIDEFIELD Estos sistemas utilizan el QED como sistema

de CAPTURA 3D y el IPP con los modulos de 3D Constructor como sistema de reconstruccion en 3D.

Estos sistemas tambien permiten hacer SEGUIMIENTOS EN EL TIEMPO , analisis de MULTIFLUOROFOROS y reconstrucciones en 3D.

ANALISIS DE 3D WIDEFIELDANALISIS DE 3D WIDEFIELD

3D Constructor contains the following modules:

3D Viewer. The 3D Viewer includes the Volume Renderer, Slicer, Measurement, and Animation features.

3D Filters. A new item, 3D Filters, adds convolution and morphological filters to Image-Pro Plus. These filters appear on the Process menu.

A new button to activate 3D Constructor will appear on your Image-Pro

Plus toolbar.
