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 detector and the restrictor whose positions are thus fixed are assembled to the body so that a circumferential edge of the detector opening part is located outside the set detection area while the restriction of the inherent detection area by the restrictor is maintained.
