Apparatus and method for electromagnetic radiation sensing

A radiation sensing apparatus, comprising:

• at least one row of micro mirrors arranged along a first direction in a first plane, each respective micro mirror in the row of micro mirrors having a radiation absorbing surface and a light reflecting area positioned at an opposite side of the radiation absorbing surface, wherein the respective micro mirror is configured to rotate along a second direction in the first plane in response to radiation absorbed in the radiation absorbing surface;
• a light directing device configured to direct a respective light ray from a light source to the light reflecting areas of the respective micro mirrors, wherein a first ray incident to a first micro mirror of the micro mirrors is of a first intensity and a second ray incident to a second micro mirror of the micro mirrors is of a second intensity, the second intensity being different from the first intensity;
• an imaging surface parallel to the first plane and facing the light reflecting area of the respective micro mirror to receive a reflected light ray of the respective light ray directed onto the light reflecting area of the respective micro mirror, the imaging surface positioned in relation with the row of micro mirrors to produce equal displacements of light rays reflected from at least two of the row of micro mirrors onto the imaging surface for equal rotations along the second direction in the row of micro mirrors;
• and
• a photodetector to capture an image projected onto the imaging surface, wherein an image sensor is configured to detect intensities of received reflective light rays and determine a respective ordering of the received reflective light rays corresponding to a ranking of positions of the micro mirrors and the intensities of the reflective light rays.
