Abstract:
An all-reflective optical system includes an all-reflective afocal module, an all-reflective imaging module and an all-reflective switching structure being operated to direct a light beam through the afocal module and the imaging module. A first position of the switching structure directs the light beam to enter the first optical end of the afocal module and exit the second optical end of the afocal module, and thereafter to enter the input optical end of the imaging module. A second position of the switching structure directs the light beam to enter the second optical end of the afocal module and exit the first optical end of the afocal module, and thereafter to enter the input optical end of the imaging module. A third position of the switching structure directs the light beam to enter the input optical end of the imaging module so that the light beam completely bypasses the afocal module.
