CPC G06F 3/013 (2013.01) [G02B 26/0833 (2013.01); G02B 26/101 (2013.01)] | 19 Claims |
1. An apparatus comprising:
a first microelectromechanical system (MEMS) scanner for steering a first input light signal in a two-dimensional pattern over a scan region, wherein the first MEMS scanner has a first scanning axis characterized by a first resonant frequency and a second scanning axis characterized by a second resonant frequency;
a detector configuration that is non-imaging and includes at least one discrete detector, wherein the detector configuration is configured to measure an intensity of a first reflected light signal from the scan region and provide the measured intensity as a first detector signal, the first reflected light signal comprising at least a portion of the input light signal;
an analog-to-digital converter (ADC) configured to convert the first detector signal into a digital signal; and
a processor configured to estimate the position of the MEMS scanner over a time period and generate an image of the scan region based on a map correlating the estimated position and the digital signal over the time period.
