Procedure: Measure the object size. Place the 20-cm lens in the lens holder and set up the lens holder at 30 cm from the object. Move the screen and obtain a sharp image. Measure the image distance and the image size. Calculate the focal length. Repeat the measurements for other object distances and complete the data table.

5. Measure the map size (diameter) of each crater in mm (if they appear elliptical because of foreshortening, measure the long diameter). Use the image scale to calculate the true size of each crater in km. Record your values in Table D. Using the objects’ reference sizes, calculate your % discrepancies in Table D.

Resolving power is a function of receptor cell size and image distance (from lens) Equation for IFOV [IFOV(rad) =L/r] The smaller the IFOV ( the higher the resolution. IFOV is a relative measure because its an angle, not a length. The angle relates the size of an object to its resolving distance. For an average person: Receptor cell=4 µm (this ...

Measure the image size as the distance between the two holes, h2, and record this value in Table III. Choose several different values of L and of d to see the effects of these variables on the parameters 2, h2 and C. Values of d should range from 2 cm to 400 cm. L should range from very small (as close as you can) to as large as can be achieved and still see the image.
