Abstract:
1. An apparatus for early diagnosis of Alzheimer, by an eye lens test, comprising: a) a light source; b) a MOEMS rapid scanning delay line coupled to the light source; c) a quasi optics chopper coupled to the MOEMS rapid scanning delay line; d) a terahertz transmitter coupled to the quasi optics chopper; e) a first quasi optics system coupled to the transmitter; f) a terahertz light output from the first quasi optics system scanned onto the mirror of a MOEMS scanner; g) a MOEMS scanner to scan the lens of the eye in two dimensions; h) a second quasi optics system optically coupled to the eye-lens under test, the second quasi optics system receiving light reflected from the eye-lens; i) a detector coupled to the second quasi optic system; j) a matching amplifier coupled to the detector and; k) a control and display system; and l) an optical arrangement system to feed a reference light from the light source and the reflected light from the eye lens to the detector for convolving collected data from the eye lens and improving the signal to noise ratio.
