![]() This enables you to go beyond generic hypothetical models and straight to physically accurate models of your particular optical prescription. Table 1: Comparison of the diffraction limited sensor and quarter wave sensor.īut with Zemax OpticStudio, we can build the optical model for our camera complete with every ding, dent, and scratch from whenever we dropped our phone. This gives us a good idea of what best- and worst-case images might look like from the same camera system with different optical aberrations. Normally in the design phase of a sensor system, all we’re comparing are levels of optical aberrations such as a perfect diffraction limited system and one with about a quarter-wave RMS error. There’s only one question you have as you’re flying over 100 kilometers above Earth, faster than the speed of sound: how good is your selfie going to look when you’re right above your hometown? And will that cracked camera lens on your phone hold up? Well, for us engineers that last part happens when the dream slides down into a nightmare, usually right before we wake up.įig 1: STK 3D Graphics window of the satellite’s orbit and the sensor’s field of view. Congratulations! You were just selected to be on the next commercial flight to outer space.
