Claim Text:
1. An imaging apparatus comprising: a light source configured to emit source light; a pre-modulator positioned in a path of the source light, the pre-modulator including a pre-modulating imaging system configured to perform coarse modulation on the source light according to image data and to emit pre-modulated light at a pre-modulator output, the pre-modulator further including a first total internal reflection prism system oriented to refract the source light into the pre-modulating imaging system and to reflect the pre-modulated light received from the pre-modulated imaging system to the pre-modulator output; relay optics positioned in a path of the pre-modulated light and configured to defocus the pre-modulated light to output defocused light; a prime modulator positioned in a path of the defocused light, the prime modulator including a prime modulating imaging system configured to generate an image using the defocused light according to the image data, the prime modulator further including a second total internal reflection prism system oriented to reflect the defocused light to the prime modulating imaging system and to refract the image received from the prime imaging system to a prime modulator output; and a compensator plate positioned between the relay optics and the prime modulator to reduce astigmatism and coma at the prime modulator.
