Etude de la formation de l'image d'un objet microscopique 3D translucide - Application à la microscopie

Abstract : We present a complete image formation model for microscopic 3D
translucent objects. In our model, we define a translucent object as a discrete repartition of refractive indexes and absorption
coefficients. To simulate the trajectory of light, we propose a
physical model using ray tracing (rays are traced from the light
source to the observer). This physical model is used to calculate the lit object space. To simulate the image generation by the optical system, we use some wave optic principles. We model the 3D transfer function of the microscope, which depends on the amount of defocusing. We first choose the focused plane, and then we calculate a simulated image using this transfer function with each plane of the lit object space that is more or less defocused. If we change the focused plane, we obtain a simulated image sequence.
