The purpose of the oscillating mirror is to improve image SNR while imaging a moving object.
The main idea is working in maximum exposure time (due to full well of the CMOS sensor) while cancelling relative movement of the object, but "freezing" its position by using moving mirror.
The oscillating mirror should cause the camera to track the object for short period of time, increasing the number of photons accumulated per pixels of the camera.
The mirror is nominally placed 45 degrees to the optical path and 45 degrees to the sensor (sensor is 90 degrees to the optical path of the lens). It moves back and forth between the exposures.
Mirror will move to beginning position in the intervals between the exposures (during the readout).
The object incorporates a multispectral bands all in visible spectrum between 433 and 885 nm (total of 8 bands).
No need to build the lens as we already have it.
Need to simulate behavior of the rays of different wavelength vs relative hit on the sensor surface at different angles of the mirror.
