Consider the imaging lens of focal length f=100mm as shown in Figure 1. An object O is placed at distance d1=200mm to the left of the lens. Where should we place an image sensor (camera) to obtain a sharp image of the object O? Is the image inverted with respect to the object or not? What is the magnification? Assume the lens has a circular aperture of diameter D=12 mm. What is the minimum feature we can resolve with the camera? Assume light is green at ~500nm. (BONUS 5 points) How would you pick the pixel size of the camera? & f m oow k i + Figure 1 F. We now add another lens of focal length f'=50mm at distance 300mm from the lens of Figure 1, as shown in Figure 2. At what distance d4 from the second lens will the image appear? Is the image inverted? What is the magnification? / ke di fe300mm >}= ds >] Figure 2 Consider light (A) with a spectral power distribution represented as S(2) oc 2 8(2-480nm) + 8(2-540nm), Where 8 is the delta function. a. Plot S(2). b. Determine the coordinates in the CIE xy chromaticity diagram. Plot the location of color A in the diagram. What would an average human call this color? c. Find the spectral power distribution of a different light (B) that is a metamer of the light A
