Abstract: Systems, methods, and apparatuses having an array of micro mirrors that rotate according to absorbed radiation and reflect light to generate light spots. In a first setting, a processor obtains an image of the light spots, determines positions of the light spots using a computationally efficient but less accurate method to calculate the intensities of radiation directed at the micro mirrors, and provides the calculated radiation. In a second setting, the processor does not determines the position; and the image is transmitted to a separate computing device to determine positions of the light spots using a computationally intensive but more accurate method to calculate the intensities of radiation directed at the micro mirrors. The system can dynamically switch between the first setting and second setting without a need to adjust hardware.

The apparatuses can include a micro-mirror chip having a plurality of light reflecting surfaces, an image sensor having an imaging surface, and a beamsplitter unit located between the micro-mirror chip and the image sensor. The beamsplitter unit includes a plurality of beamsplitters aligned along a horizontal axis that is parallel to the micro-mirror chip and the imaging surface. The beamsplitters implement the sequential beam splitting. Because of the structure of the beamsplitter unit, the height of the arrangement of the micro-mirror chip, the beamsplitter unit, and the image sensor is reduced such that the arrangement can fit within a mobile device.
