6. [10] A lens with focal length 2cm is placed 4cm from a translucent cancer cell on a slide and 4cm from a sensor. The cell is illuminated with light of wavelength 800 nm. For simplicity, suppose the cell transparency is the sum of a disk function and an ellipse function: to(x, y) circ = T To +e(x, y), e(x, y) = where ro= 100 um, rx = 200 um, ry cell has recently divided?) Determine the optical intensity recorded on the sensor. 2 x-xo + y yo 1, 0, otherwise, rx ry 2 1 = = 100 um, o = 300, and yo = 0. (If you sketch this out, it might look like the Hint. Use FT properties, not integration!
