Abstract: A camera includes a first lens configured to focus incoming light onto a reflective slit assembly. The reflective slit assembly comprises an elongated strip of reflective material configured to reflect some but not all of the incoming light as return light. The first lens is configured to at least partially collimate the return light from the elongated strip of reflective material. A first mirror is configured to reflect the return light from the first lens. A second mirror is configured to reflect the return light from the first mirror. An optical element is configured to separate the return light from the first mirror as a function of wavelength. A second lens is configured to focus the return light from the optical element onto a first detector. The first detector is configured to measure intensities of the return light as a function of two dimensional position on the first detector.
