7) A digital frame camera consists of 4096 x 4096 array of CCD elements at a pixel size of 9 µm square. The nominal focal length of the camera is 50 mm. What is the maximum spatial frequency that can be detected (at image scale)? What is the angular field of view (FOV) for this camera (8 points)?

A digital camera uses a CCD detector that is $7.2 \mathrm{mm}$ wide and $5.3 \mathrm{mm}$ tall. a. If the detector is rated for " 4.0 megapixels" and the pixels are equally spaced, what is the distance between the centers of adjacent pixels on the CCD chip? (Use Figure 26.23 to model the arrangement of CCD pixels and ignore any space between the edges of adjacent pixels.) b. When an object is at infinity, the lens is found to be $1.5 \mathrm{cm}$ from the CCD detector. What is the focal length of the lens? c. If an object is placed $30 \mathrm{cm}$ from the lens, what spacing between the lens and the CCD detector is required for the image to be at the detector?

A CCD camera chip of dimensions 7x7 mm, and having 1024x1024 elements, is focused on a square, flat area located 0.5 m away. How many line pairs per mm will this camera be able to resolve? The camera is equipped with a 35-mm lens. (Hint: Model the imaging process as in Fig. 2.3, with the focal length of the camera lens substituting for the focal length of the eye.) FIGURE 2.3: Graphical representation of the eye looking at a palm tree 15m away. Point C is the optical center of the lens.
