It is a technical difficulty to test the unsymmtrical optical surfaces in non-contact methods. But we can do it using computer-generated holograms (CGH). The principle and design of the CGH have been discussed in the paper. Take the cubic suface as an example
The order separation of the CGH is analyzed theoretically and the simulation result of the order separation is given in the paper. We develop the binary process of the continuous CGH phase function and get the sample of the amplitude CGH. A CGH for testing a cubic phase plate with duty cycle 0.5 is fabricated by using e-beam lithographic techniques. In this situation
the contrast of the interference fringe pattern can achieve a level of 99.4% by calculation. 2012 IEEE.

The Long Trace Profiler (LTP) is a precision surface slope error measurement instrument used in synchrotron radiation optics for many years. By making some modifications to the LTP system
we developed a co-path scanning LTP (CSLTP) system to test the cylindrical aspherical surface which used in X-ray space optics. To reduce the mistake caused by air turbulence and manufacture faults of optical elements used
the CSLTP is designed with the least difference between the testing beam path and the reference beam path. Also
it uses multiple-beam interference but double beam interference to reduce the width of beam fringe. This improves the position precision of the beam fringe on the image plane. 2010 SPIE.

In order to solve the conductive ring module's interference problems
measured the electromagnetic radiation of Power drive module
and used test results analysis the electromagnetic compatibility of the conductive ring
identified and implemented appropriate EMC (electromagnetic compatibility) measures. When optical tracking system working
test equipment can not be fixed. Therefore
from the electromagnetic radiation theory
the paper analyzed the electromagnetic radiation of the power drive module. From it
determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results
calculate the interference voltage of wire in Conductive ring
and then determine the corresponding EMC method. The results show that
when The power drive module Radiate Electromagnetic waves
wires would coupled common mode interference voltage
its frequency is 3MHz
amplitude is about 10V
it would interfered the operation of sensor. By reducing the area of ground loops
used shielded cables
final rule out the interference. 2010 IEEE.
