&quot;B. Limitations of FlatCam<p>...<p>Achievable image&#x2F;angular resolution. Our current prototypes
have low spatial resolution which is attributed to two
factors. First, it is well known that angular resolution of
pinhole cameras and coded aperture cameras decreases when
the mask is moved closer to the sensor [6]. This results
in an implicit tradeoff between the achievable thickness and
the achievable resolution. &quot;<p>Also the images speak for themselves - all very blurry.
