#$%^&*AU2016210761A120170323.pdf#####ABSTRACT An anti-aliasing photodetector system for a powered ophthalmic device, such as a contact lens, may be utilized for any number of functions. The anti-aliasing 5 photodetector system converts current from an array of photodetectors into a voltage for use in other aspects of the powered ophthalmic device. The anti-aliasing photodetector system comprises a photodiode array including a plurality of individual photodiodes, an integrate-and-hold circuit, including a capacitor and switch to convert current to voltage, and an analog-to-digital converter. The anti-aliasing photodetector system provides for o low power consumption, a wide dynamic range, noise rejection, and is capable of detecting incident ambient visible light as well as incident infrared light.1/7 FIG. 1 Contact Lens Power Source 108 110 Actuator 112 Photodetector Signal - System System Processing Controller 101 102 104 106 100
