96 TOF - General inquiry

Question

Hello Gentlemen 
 I believe that deploying my customer's inquiry here will help leverage support globally. Many questions are of general interest. 
 Thanks in advance for your attention. 
 Currently I am supporting a new design and customer has already 96 TOF board and also ADDI9036 full datasheet. They are aware of this channel but I also aligned with them to deliver here the questions, since I have been with ADI support many years and can better filter the inquiry in order to make a more accurate support. 
 I have dig the forum and below some interesting questioning: 
 
 Where is the starting point of measurement inside the sensor in the 96 TOF kit? Is it somewhere in the Panasonic TOF sensor MN34906BLJ5Z 
 Can you please share with me the mechanical drawings of the kit and specifications of the lens used? Please e-mail to Juliano.Cioffi @ analog 
 The kit has three operating modes near, medium and far; What are the modulation frequencies in the different modes shown, or what is the main lighting modulation frequency of the kit ? 
 Is it possible to use two or more modulation frequencies? 
 How can the modulation frequency can be changed? 
 Will this improve resolution and precision of the distances considering the platform? 
 
 Many Thanks 
 Att 
 Juliano

1. The Panasonic CCD sensor is the first device in the signal chain. 
 2. This is the lens that's being used in the kit: https://www.jcdo.com/products/j6920 . The mechanical parameters of the kit can be taken from the layout files available for download on the wiki: https://wiki.analog.com/resources/eval/user-guides/ad-96tof1-ebz/laserboard , https://wiki.analog.com/resources/eval/user-guides/ad-96tof1-ebz/afeboard 
 3. The system sends out trains of pulses, each pulse being 22ns long for the near and medium modes, respectively 33ns long for the far mode. 
 4 & 5. The modulation type cannot be changed, but the number of pulses that are being sent out for a frame capture can be changed. 
 6. A higher pulse count per frame will result in longer sensing range. The resolution of the system is 1mm for Near mode, 1.5mm for Medium mode, 2mm for Far mode, but the specified accuracy is < 2% of the measured distance. The accuracy can be improved with better optics, more precise calibration, higher laser performance for sharper light pulse edges.)

Unfortunately we don't have a CAD model for the boards.
