A method of testing figure quality of a convex mirror in which an optical quality substrate material is used. The substrate has a front convex surface that has to be polished and figured to high accuracy, typically λ/10 (HeNe), and a rear concave surface which only needs to be polished and figured to moderate surface figure accuracy, typically about 1-λ (HeNe). Three separate interferometric null tests are then carried out to produce three independent sets of optical path difference (OPD) data. Null lenses, or nulling computer generated holograms (CGHs), are designed and used as needed in each test setup so that spherical aberration is corrected. All three separate interferometric tests are either ideal null tests, or near null tests. From the three sets of OPD data, surface figure errors on the rear and front surfaces of the test optic, h₁(x_i,y_j) and h₂(x_i,y_j), are calculated as well as the OPD error OPDI(x_i,y_j) introduced by refractive index inhomogeneity in the substrate material. The rear surface is then corrected, generally using a computer-controlled polishing machine, to reduce rear surface errors h_i(x_i,y_j) to a manageably small level. The front convex surface of the test optic is then corrected to reduce surface figure error h₂(x_i,y_j) to within some specified amount. The front mirror surface can be figured to any required accuracy in spite of residual surface figure error in the rear surface, h₁(x_i,y_j), and the effects of refractive index inhomogeneity in the substrate material OPDI(x_i,y_j). The convex front surface is then coated with a reflective coating to produce the finished convex mirror.

An UART receives asynchronous transmission serial data based on a baud-rate clock from a DTE. An MPU analyzes the data received by the UART. A baud-rate generating portion generates the baud-rate clock to be output to the UART in accordance with instructions from the MPU. A first counter measures the span of the start bit of the first character of an AT command transmitted from the DTE based on instructions from the MPU. A decoder receives a measurement result of the first counter, outputs frequency-dividing data for producing a clock for sampling the first character, and also outputs, when the rate of the start bit is more than a preset value, a flag indicating this matter. A second counter selects, in accordance with whether or not the flag is has been set, the frequency-dividing data from either the decoder or the MPU, and produces the sampling clock. A shift register receives data subsequent to the start bit of the first character based on the sampling clock from the second register, holds the received data, which data is then read by the MPU.
